In Various Regions Of The World The EFA Goals Are Frustrated By - 1
In Various Regions Of The World The EFA Goals Are Frustrated By - 1 In Various Regions Of The World The EFA Goals Are Frustrated By Social, Cultural And Economic â" Essay Example > EDUCATION FOR ALL GOALSEducation For All (EFA) are standards set apart to govern education policies systems, and structures of 164 countries that agreed to take part. Indeed, they were intended to run between 2000 and 2015 culminating in 15 years. As a benchmarking tool, six goals were set to regulate and define a successful system by 2015 (Hutton 2014). These goals included: the expansion of early childhood and care education and achievement of universal primary education that would be free. Also, it provided guaranteed access to vocational and life skills to youth and adults, attaining 50% reduction illiteracy in adults by 2015. More goals included achieving gender parity and equality between male and female counterparts and further improving the quality of education given to children, adults, and youth (Sayed and Ahmed 2015). However, Nigeria has been experiencing a lot of challenges in meeting this goal despite a consistent increase in its per capita income up to 2014. In ranki ngs of specific targets, Nigeria has failed and has been viewed far from achieving any of the goals. Indeed, failure may be attributed to some challenges, which the country faces that include poverty, lack of sufficient funding from the government, corruption, high student to teacher ratio and child labour (Ametepee and Anastasiou 2015). Also, insecurity in the northern regions of the country, poor infrastructure and cultural barriers such as female hindrance from participating in education have hindered the country its EFA goals. In this study, the focus will lie majorly on goal two which is the attainment of free universal education, and goal six which discusses improving the quality of education offered. It will also address the frustrating factors to this goal and their impact. Nevertheless, the study will first examine the UNESCO contextual background. Also, it will review the Nigerian education system and how it has evolved in brief and how the neighbouring countries are far ing in the quest to achieve these goals. However, EFA study has been motivated by the need for education to be part of the core requirements of all human beings. It also aims at enhancing the growth of the education sector in Nigeria after the inception of the education for all goals, the challenges it has faced and the way forward to achieve these aims. In essence, it is vital for education to be integrated into oneâs life since it enables people to improve their quality of life by increasing their creativeness. Also, adequate education improves individual bargaining power and eventually progress the economic performance of the nation. When an education system fails or is unable to meet the global standards or needs, necessary action must be put into place to ensure that the problem is corrected before it becomes a major issue. Nigeria, for example, seems to be facing a myriad of challenges and levels of illiteracy have been increasing rapidly. These problems have caused the fo rmer and if mitigated, the education sector in the country will thrive. United Nations under UNESCO (United Nations Education, Scientific and Cultural Organisation) initiated the EFA study. Its main aim was to provide efficient learning requirements to children, youth, and adults from all walks of life from both genders. These goals were created in correspondence to the Millennium Development Goals (MDGs) two and three which were concerned with universal primary education and gender parity (Roby, Erickson and Nagaishi 2016). The goals commenced in 2000 as a way of improving the educational sector that was ailing. Therefore, UNESCO was chosen to coordinate and oversee the memberâs efforts in developing the education sector in their respective countries. In fact, through the global monitoring reports, UNESCO reports on the progress of the goals in various countries and provides solutions. In the recent reports, UNESCO has shown that majority countries have not achieved their target s entirely, but there is a steady rise towards its achievement. According to the Global Monitoring Reports by UNESCO, Nigeria is ranked 103, in the Education Development Index, out of 163 nations who signed up the EFA goals. On goal one, which involves expanding early childhood care education, 47% of countries, have already achieved the goal and 8% percent are adjacent to achieving the goal. However, 20% are very far from achieving the goal which includes Nigeria. On the second goal which is about attaining universal primary education, 52% percent have already reached it with 10 % percent close (UNESCO 2013). However, Nigeria and other nations make up 38 percent which has a long way to go. Goal three, which provides access to vocational and life skills, to be equitable has achieved poor performance in many nations with less than half of adolescents enroling in secondary schools, including Nigeria. The fourth goal which aims at decreasing adult illiteracy by 50% percent in 2015 has achieved 25% fulfilment with 32 percent being very far from attaining it. In Nigeria, for example, 51 percent of Nigerian adults are illiterate. On obtaining gender parity and equality which is the 5th goal, many countries, especially in the sub-Saharan region, are yet to achieve it. Specifically, Nigeria is yet to achieve both at the primary and secondary level with more males attending school than females. Female illiteracy is a result of early marriage and premature pregnancy. Further, there is also lack of teacher training on how to approach gender sensitive issues. The last goal addresses the quality of education and improvement. In fact, efficient education has not been achieved in majority countries. However, many states are still on track and will achieve the goals in due course.

Is Teaching a Profession - 2328 Words
All professions have an identifiable knowledge base. Teaching has no such knowledge base, therefore, it is not a profession Discuss this statement. There are different characteristics of what a profession entails of. Some characteristics, such as full graduate training are based on the more known professional modes such as law, medicine and engineering. The majority of critics have agreed on the similar aspects of an occupational group acquiring: a knowledge base, expertise in their field, a sense of autonomy and responsibility which makes them a profession. In regards to teaching, it has sufficient evidence to produce these requirements which enables them to be recognised as a profession in society. Professions are known to have theâ⬠¦show more contentâ⬠¦For an occupation to become a profession they need to be able to produce these characteristics of uniqueness which will lead to increasing their identity in society. From what makes up a profession, teachers are able to; under this criterion with other additional features become what is called a profession. Teachers and education have gone through changes in which their identity of being a profession has either been deprofessionalised or improved to suit societys and the occupations needs. It has been increasingly more evident that teaching is a profession. Throughout the history of teaching, there has been progress, which gives reason to consider that teaching is a profession. The old teaching profession (Sachs, 2003, p. 8) includes teachers being given an exclusive membership. This notion of membership means that only people within this occupational group are permitted. Membership becomes restricted to individuals who meet their standards, just like other professions such as doctors. The disadvantage of this was that it was too slow to react to the changing demands of society of inclusion and exclusion of individuals. Although teaching does have the traditional feature of professions, it also has the negative effect which, in end, brought the fall of the old teaching profession and introduced several improvements to identify teaching as a profession.

A Clockwork Orange Summary Free Essays
Synopsis: Young Alex and his gang members (Dim, Pete and Georgie) go on a rampage around the futuristic city in London. In the book what we call evil is actually a form of art to Alex. Alex loves art itself, particularly classical music. We will write a custom essay sample on A Clockwork Orange: Summary or any similar topic only for you Order Now To Alex, the delight he finds in classical music is closely related to the joy he feels during acts of violence. The Stateââ¬â¢s destruction of Alexââ¬â¢s ability to make his own moral choices represents a greater evil than any of Alexââ¬â¢s crimes, since turning Alex into an automaton ultimately sanctions the notion that human nature is dispensable. Alex truly grows as a human being only in the last chapter, after the government removes his conditioning and he can see the error of his ways for himself, without the prompting of an external, controlling force. The slang used by the ââ¬Å"Droogsâ⬠represents the social gap between youth and the elders of society. Aspects: Music: Music in this book is one of the main aspects. Music affects everyone in a different way. Alex when he listens to symphonies especially Ludwig Van Beethoven, he gets stimulated to do more violence. Good is bad and bad is good: A regular teens would go to school and have a part time job to make money. As we would think school, having a job, working for yourself is good for you. In a Clockwork Orange everything is switched around. Basically what the young adults find good is like robbing stores, raping women on the street, having gang fights, the good old ultra violence. Satire: The dystopia ofà A Clockwork Orangeà has a very satirical tone. The aspect of satire in the novel is in the form of political commentary. Alex and his gang deprive the community of moral choice and free will, limiting their personal freedoms. In this way, Anthony Burgess conveys an anti-totalitarian message in the novel. The futuristic dystopian society of the novel is a completely exaggerated claim of what a totalitarian government would lead to. In an attempt to prove the point that a deprivation of personal freedoms would be catastrophic to the world, Burgess paints a picture with absolutely no happiness, a picture painted satirically. Theme: If personal freedom is a justifiable sacrifice for comfort and social stability. His treatment shows that government would rather have a faceless society that shuns emotion and motive. Maturity: When Alex in the end shows that he wants too mature into an adult when he confronts or meets Pete. How to cite A Clockwork Orange: Summary, Papers

Spotted Horses Vs Mule In The Yard free essay sample
Patched Horses Vs. Mule In The Yard Essay, Research Paper Patched Horses Vs. Mule in the Yard William Faulkner wrote two short narratives, which are likewise in many facets. Patched Horses and Mule in the Yard are short narratives that both involve amusing animate being pursuits and fiscal minutess. Even though the narratives are written by the same writer, have similar features, and portion similar secret plan characteristics, they are wholly different narratives. The narratives are both illustrations of interpretative literature, nevertheless Patched Horses is a more interpretative short narrative than Mule in the Yard because Spotted Horses fits Perrine s profile of interpretative literature, and Mule in the Yard seems to retroflex Perrine s profile of flight literature. Harmonizing to Laurence Perrine in his 7th edition of Literature: Structure, Sound and Sense he states the definition of interpretative literature is Literature written to intensify and broaden and sharpen our consciousness of life. We will write a custom essay sample on Spotted Horses Vs Mule In The Yard or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Interpretative literature is non candy coated. It allows its readers to see the tests and trials of life. By utilizing diagrammatically realistic secret plans and terminations, which are consistent to those in existent life, interpretative literature achieves a higher literary value than escape literature. Interpretative literature allows its reader excessively step out of the fantasy universe they might be populating in and concentrate on what the universe is truly approximately. One might state an interpretative narrative provides insight to understanding. Not merely understanding of ourselves, but our neighbours, friends, household or anyone else we might meet. Escape literature is the complete antonym of interpretative literature. Escape literature is written strictly for amusement. Escape literature takes it s reader out of the existent universe and into a fantasy universe where everything plants and happens merely like we want it to. This is a universe where the stoping ever has closing. Escapist writers barely of all time stop on a bad note. They want the reader to go forth the pages of their narrative satisfied, and holding a sense of contentment. Perrine s illustration of flight literature is Cinderella. Cinderella s life goes from shreds to wealths in one dark. She marries a prince and lives merrily of all time after. Harmonizing to Perrine the most common outlooks of flight literature readers are the sympathetic heroes or heroines, the suspenseful secret plan which one exciting event returns another, the resolved happy result, and the subject. Escape literature subjects confirm the reader s old sentiments of the universe. Readers of flight literature read for pleasance non to garner cognition on how to last in the existent universe. The difference between flight literature and interpretative literature has nil to make with the absence or presence of ethical motives, facts, phantasy, or history. The chief difference between the two is the intent for which the narrative is written. Mule in the Yard by William Faulkner is an interpretative narrative. Howe ver, Patched Horses is a more interpretative narrative. Even though Mule in the Yard is interpretative, it has a few flight literature qualities. The supporter for Mule in the Yard was Mrs. Hait, and the adversary was Snopes. The cardinal struggle between the two of them was that Snopes had succeeded in killing Mrs. Hait s hubby and acquiring off with it. Justice being served resolved the struggle. Snope s fraud efforts where discovered by the insurance bureau, and Mrs. Hait got her retaliation by hiting his mule. This explains your typical reader friendly escapist stoping. Where as, in Patched Horses, the stoping is more unsolved. Patched Horses uses a more true to life state of affairs where what the reader would pigeonhole as an unhappy or undetermined stoping because justness was non served and good did non predominate over immorality. Patched Horses is a more interpretative narrative than Mule in the Yard because of the plausibleness of the happenstances. The full transition about the fire in Mule in the Yard seems impossible. The opportunities are slender to none of Mrs. Hait go forthing the pail of hot coals and the heap of fire priming pitch pine acerate leafs set following to the steps taking down to the marketer, where Snopes merely so happened to go forth the door opened. None of it truly seems possible. Patched Horses has a few happenstances, but they are slightly problematic. The fact that Eula Varner was pregnant and had to acquire married, so Flem Snopes married her to be able to take advantage of her household more exhaustively was one case of happenstance. We know from experience many people use their place on to travel up in the universe. By pull stringsing the people in a state of affairs, one can many times either net income or better them as a consequence. Flem may hold merely been working to bette r himself by replying the door while chance was strike harding. This may hold non been a happenstance. William Faulkner may hold merely used this case to assistance in his word picture of Flem Snopes. Another of Perrine s outlooks of flight literature can be described as a busy secret plan. This is where something is ever go oning throughout the narrative to maintain the readers attending. The secret plan used in Mule in the Yard resembles the description. There is ever something traveling on between Mrs. Hait and Snopes. Mrs. Hait s hubby gets killed, she and Snopes fight over money, Mrs. Hait s house burns down, she and Snopes fight over money once more, Snopes gets busted for fraud by the insurance company, and Mrs. Hait shoots a mule all this happens in 90 paragraphs. Once once more, Patched Horses is proved to be the more interpretative of the two narratives because it s secret plan was non written for amusement. There is no suspense in Patched Horses. Mule in the Yard is non a bad narrative. It is really an interpretative piece of literature. There are some cases where it could be marginal flight literature, but overall it is interpretative. When compared to Spotted Horses, it is the more dreamer of the two.

Solid Geometry on SAT Math The Complete Guide
Solid Geometry on SAT Math The Complete Guide SAT / ACT Prep Online Guides and Tips Geometry is the branch of mathematics that deals with points, lines, shapes, and angles. SAT geometry questions will test your knowledge of the shapes, sizes, and volumes of different figures, as well as their positions in space. 25-30% of SAT Math problemswill involve geometry, depending on the particular test. Because geometry as a wholecovers so many different mathematical concepts, there are several different subsections of geometry (including planar, solid, and coordinate). We will cover each branch of geometryin separate guides, complete with a step-by-step approach to questions and sample problems. This articlewill be your comprehensive guide to solid geometry on the SAT. Weââ¬â¢ll take you through the meaning of solid geometry, the formulas and understandings youââ¬â¢ll need to know, and how to tackle some of the most difficult solid geometry problems involving cubes, spheres, and cylinders on the SAT. Before you continue, keep in mind that there will usually only be 1-2 solid geometry questions on any given SAT, so you should prioritize studying planar (flat) geometry and coordinate geometry first. Save learning this guide for last in terms of your SAT math prep. Before you descend into the realm of solid geometry, make sure you are well versed in plane geometry and coordinate geometry! What is Solid Geometry? Solid geometry is the name for geometry performed in three dimensions. It means that another dimension- volume- is added to planar (flat) geometry, which only uses height and length. Instead of flat shapes like circles, squares, and triangles, solid geometry deals with spheres, cubes, and pyramids (along with any other three dimensional shapes).And instead of using perimeter and area to measure flat shapes, solid geometry uses surface area and volume to measure its three dimensional shapes. A circleis a flat object. This is plane geometry. A sphere is a three-dimensional object. This is solid geometry. On the SAT, most of the solid geometry problems are located at the end of each section. This means solid geometry problemsare considered some of the more challenging questions (or ones that will take the longest amount of time, as they often need to be completed in multiple pieces).Use this knowledgeto direct your study-focus to the most productive avenues. If you are getting several questions wrong in the beginning and middle sections of each math section, it might be more productive for you to take the time to first refresh your overall understanding of the math concepts covered by the SAT. You can alsocheck out how to improve your math scoreor refresh your understanding of all the formulas youââ¬â¢ll need. Note: most of the solid geometry SAT Math formulas are given to you on the test, either in the formulas box or on the question itself. If you are unsure which formulas are given or not given in the math section, refresh your formulas knowledge. This is the formula box you'll be given on all SAT math sections. You are given the formulas for both the volume of a rectangular solid and the volume of a cylinder. Other formulas will often be given to you in the question itself. But whilemany of the formulas are given, it is still important for you to understand how they work and why. So donââ¬â¢t worry too much about memorizing them, but do pay attention to them in order to deepen your understanding of the principles behind solid geometry on the SAT. In this guide, Iââ¬â¢ve divided the approach to SAT solid geometry into three categories: #1: Typical SAT solid geometry questions #2: Types of geometric solids and their formulas #3: How to solve an SAT solid geometry problem with our SAT math strategies Solid geometry adventure here we come! Typical Solid Geometry Questions on the SAT Before we go through the formulas you'll need to tacklesolid geometry, it's important to familiarize yourself with the kinds of questions the SAT will ask you about solids. SAT solid geometry questions will appear in two formats: questions in which you are given adiagram, and word problem questions. No matter the format, each type of SAT solid geometry questionexiststotestyour understanding of the volume and/or surface area of a figure. You will be asked how to find the volume or surface area of a figure or you'll be asked to identify how a shape's dimensions shift and change. Diagram Problems A solid geometry diagram problem will provide you with a drawingof a geometrical solid and ask you to find a missing element of the picture. Sometimes they will ask you to find the volume of the figure, the surface area of the figure, or the distance between two points on the figure. They may alsoask you to compare the volumes, surface areas, or distances of several different figures. This is a typical "comparing solids" SAT question. We'll go through how to solve it later in the guide. Word Problems Solid geometry word problemswill usually ask you tocomparethe surface areas or volumes of two shapes. They will often giveyou the dimensions of one solid and then tell youto compare its volume or surface area to a solid with different dimensions. By how many cubic feet is a box with a height of 2inches, a width of 6 inches, and a depth of 1 inch greater than a cylinder with a height of 4 inches and a diameter of 6 inches? This is a typical word problem question that might appear in the grid-in section of the SAT math Other word problems mightask you to contain one shape within another. This is just another way of getting you to think about a shape's volume and ways to measure it. What is the minimum possible volume of acube, in cubic inches,thatcouldinscribe a sphere with a radius of 3 inches? A) $12âËÅ¡3$ (approximately $20.78$) B) $24âËÅ¡3$ (approximately $41.57$) C) $36âËÅ¡3$ (approximately $62.35$) D) $216$ E)$1728$ This is a typical inscribing solids word problem. We'll go through how to solve it later in the guide. Solid geometry word problemscan be confusing to many people, because it can be difficult to visualize the question without apicture. As always with word problems that describe shapes or angles, make the drawing yourself! Simplybeing able to seewhat a question is describing can do wonders to help clarify the question. Overall Style of Solid Geometry Questions Every solid geometry question on the SAT is concerned with either the volume or surface area of a figure, or the distance between two points on a figure. Sometimes you'll have to combine surface area and volume, sometimes you'll have to compare two solids to one another, but ultimately all solid geometry questions boil down to these concepts. So now let's go through how to find volumes, surface areas, and distances of all the different geometric solids on the SAT. A perfect example of geometric solidsin the wild Prisms A prism is a three dimensional shape that has (at least) two congruent, parallel bases. Basically, you could pick up a prism and carry it with its opposite sides lying flat against your palms. A few of the many different kinds of prisms. Rectangular Solids A rectangular solid is essentially a box. It has three pairs of opposite sides that are congruent and parallel. Volume $\Volume = lwh$ The volume of a figure is the measure of its interior space. $l$ is the length of the figure $w$ is the width of the figure $h$ is the height of the figure Notice how this formula is the same as findingthe area of the square ($A = lw$) with the added dimension of height, as this is a three dimensional figure First, identify the type of question- is it asking for volume or surface area? The question asks about the interior space of a solid, so it's a volume question. Now we need to finda rectangular volume, but this question is somewhat tricky. Notice that we're finding out how much water is in a particular fish tank, but the water does not fill up the entire tank. If we just focus on the water, we would find that it has a volume of: $V = lwh$ = $(4)(3)(1) = 12\cubic\feet$ (Why did we multiply the feet and width by 1 instead of 2? Because the water only comes up to 1 foot; it does not fill up the entire 2 feet of height of the tank) Nowwe are going to put that 12 cubic feet of water into a second tank. This second tank has a total volume of: $V = lwh$ = $(3)(2)(4) = 24\cubic\feet$ Although the second tank can hold 24 cubic feet of water, we are only putting in 12. So $12/24 = 1/2$. The water will come up at exactly half the height of the second tank, which means the answer is D, 2 feet. Either way, those fish won't be very happy in half a tank of water Surface Area $\Surface\area = 2lw + 2lh + 2wh$ In order to find the surface area of a rectangular prism, you are finding the areas for all the flat rectangles on the surface of the figure (the faces) and then adding those areas together. In a rectangular solid, there are six faces on the outside of the figure. They are divided into three congruent pairs of opposite sides. If you find it difficult to picture surface area, remember that a die has six sides. So you are finding the areas of the three combinations of length, width, and height (lw, lh, and wh), which you then multiply by two because there are two sides for each of these combinations.The resulting areas are then all added together to getthe surface area. Diagonal Length $\Diagonal = âËÅ¡[l^2 + w^2 + h^2]$ The diagonal of a rectangular solid is the longest interior line ofthe solid. It touches from the corner of one side of the prismto the opposite corner on the other. You can find this diagonal by either using the above formula or by breaking up the figure into two flat triangles and using the Pythagorean Theorem for both. You can always do this is you do not want to memorize the formula or if you're afraid of mis-remembering the formula on test day. First, find the length of the diagonal (hypotenuse) of the base of the solid using the Pythagorean Theorem. $c^2 = l^2 + w^2$ Next, use that length as one of the smaller sides of a new triangle with the diagonal of the rectangular solid as the new hypotenuse. $d^2 = c^2 + h^2$ And solve for the diagonal using the Pythagorean Theorem again. Cubes Cubes are a special type of rectangular solid, just like squares are a special type of rectangle A cubehasa height, length, and width that are all equal. The six faces on a cube's surface are also all congruent. Volume $\Volume = s^3$ $s$ is the length of the side of a cube (any side of the cube, as they are all the same). This is the same thing as finding the volume of a rectangular solid ($v = lwh$), but, because their sides are all equal, you can simplify it by saying $s^3$. First, identify what the question is asking you to do. You're trying to fit smallerrectangles into a larger rectangle, so you're dealing with volume, not surface area. Find the volume of the larger rectangle (which in this case is a cube): So you can use the formula for the volume of a cube: $\Volume = s^3$ = $6^3 = 216$ Or you can use the formula to find the volume of any rectangular solid: $\Volume = lwh$ = $(6)(6)(6) = 216$ Now find the volume of one of the smaller rectangular solids: $\Volume = lwh$ = $(3)(2)(1) = 6$ And divide the larger rectangular solid by the smaller to find out how many of the smaller rectangular solids can fit inside the larger: $216/6 = 36$ So your final answer is D, 36 SurfaceArea $\Surface\area = 6s^2$ This is the same formulas as the surface area for a rectangular solid ($SA = 2lw + 2lh + 2hw$). Because all the sides are the same in a cube, you can see how $6s^2$ was derived: $2lw + 2lh + 2hw$ = $2ss + 2ss + 2ss$ = $2s^2 + 2s^2 + 2s^2$ = $6s^2$ Diagonal Length $\Diagonal= sâËÅ¡3$ Just as with the rectangular solid, you can break up the cube into two flat triangles and use the Pythagorean Theorem for both as an alternative to the formula. This is the exact same process as finding the diagonal of a rectangular solid. First, find the length of the diagonal (hypotenuse) of the base of the solid using the Pythagorean Theorem. Next, use that length as one of the smaller sides of a new triangle with the diagonal of the rectangular solid as the new hypotenuse. Solve for the diagonal using the Pythagorean Theorem again. Cylinders A cylinder is a prism with two circular bases on its opposite sides Notice how this problem only requires you to know that thebasic shape of a cylinder.Draw out the figure they are describing. If the diameter of its circular bases are 4, that means its radius is 2. Now we have two side lengths of a right triangle. Use the Pythagorean Theorem to find the length of the hypotenuse. $2^2 + 5^2 = c^2$ = $29 = c^2$ = $c = âËÅ¡29$, or answer C Volume $\Volume = Ãâ¬r^2h$ $Ãâ¬$ is the universal constant, also represented as 3.14(159) $r$ is the radius of the circular base. It is any straight line drawn from the center of the circle to the circumference of the circle. $h$ is the height of the circle. It is the straight line drawn connecting the two circular bases. This problem requires you to understand how to get both the volume of a rectangular solid and the volume of a cylinder in order to compare them. A right circular cylinder with a radius of 2 and a height of 4 will have a volume of: $V = Ãâ¬r^2h$ = $Ãâ¬(2^2)(4) = 16Ãâ¬$ or $50.27$ The volumes for the rectuangular solids are found by: $V = lwh$ So solid A has a volume of $(3)(3)(3) = 27$ Solid B has a volume of $(4)(3)(3) = 36$ Solid C has a volume of $(5)(4)(3) = 60$ Solid D has a volume of $(4)(4)(4) = 64$ And solid E has a volume of $(4)(4)(3) = 48$ So the answer is E, 48 Surface Area $\Surface\area = 2Ãâ¬r^2 +2Ãâ¬rh$ To find the surface area of a cylinder, you are adding the volume of the two circular bases ($2Ãâ¬r^2$), plus the surface of the tube as if it were unrolled ($2Ãâ¬rh$). The surface of the tube can also be written as $SA = Ãâ¬dh$, because the diameter is twice the radius. In other words, the surface of the tube is the formula for the circumference of a circle with the additional dimension of height. Non-Prism Solids Non-prism solids are shapes in three dimensions that do not have any parallel, congruent sides. If you picked these shapes up with your hand, a maximum ofone side (if any) would lie flat against your palm. Cones A cone is similar to a cylinder, but has only one circular base instead of two. Its opposite end terminates in a point, rather than a circle. There are two kind of cones- right cones and oblique cones. For the purposes of the SAT, you only have to concern yourself with right cones. Oblique cones are restricted to the math I and II subject tests. A right cone has an apex (the terminating point on top) that sits directly above the center of the coneââ¬â¢s circular base. When a height ($h$) is dropped from the apex to the center of the circle, it makes a right angle with the circular base. Volume $\Volume = 1/3Ãâ¬r^2h$ $Ãâ¬$ is a constant, written as 3.14(159) $r$ is the radius of the circular base $h$ is the height, drawn at a right angle from the coneââ¬â¢s apex to the center of the circular base The volume of a cone is $1/3$ the volume of a cylinder. This makes sense logically, as a cone is basically a cylinder with one base collapsed into a point. So a coneââ¬â¢s volume will be less than that of a cylinder. Surface Area $\Surface\area = Ãâ¬r^2 + pirl$ $l$ is the length of the side of the cone extending from the apex to the circumference of the circular base The surface area is the combination of the area of the circular base ($Ãâ¬r^2$) and the lateral surface area ($Ãâ¬rl$) Because right cones make a right triangle with side lengths of: $h$, $l$, and $r$, you can often use the pythagorean theorem to solve problems. Pyramids Pyramids are geometric solids that are similar to cones, except that they have a polygon for a base and flat, triangular sides that meet at an apex. There are many types of pyramids, defined by the shape of their base and the angle of their apex, but for the sake of the SAT, you only need to concern yourself with right, square pyramids. A right, square pyramid has a square base (each side has an equal length) and an apex directly above the center of the base. The height ($h$), drawn from the apex to the center of the base, makes a right angle with the base. Volume $\Volume = 1/3\area\of\the\base * h$To find the volume of a square pyramid, you could also say $1/3lwh$ or $1/3s^2h$, as the base is a square, so each side length is the same. Spheres A sphere is essentially a 3D circle. In a circle, any straight line drawn from the center to any point on the circumference will all be equidistant. This distance is the radius (r). In a sphere, this radius can extend in three dimensions, so all lines from the surface of the sphere to the center of the sphere are equidistant. Volume $\Volume = 4/3Ãâ¬r^3$ Inscribed Solids The most common inscribed solids on the SAT will be: cube inside a sphere and sphere inside a cube. You may get another shape entirely, but the basic principles of dealing with inscribed shapes will still apply. The question is most often a test ofYouââ¬â¢ll often have to know the solid geometry principles and formulas for each shape individually to be able to put them together. When dealing with inscribed shapes, draw on the diagram they give you. If they donââ¬â¢t give you a diagram, make your own!By drawing in your own lines, youââ¬â¢ll be better able to translate the three dimensional objects into a series of two dimensional objects, which will more often than not lead you to your solution. Understand that when you are given a solid inside another solid, it is for a reason. It may look confusing to you, but the SAT will always give you enough information to solve a problem. For example, the same line will have a different meaning for each shape, and this is often the key to solving the problem. So we have an inscribed solid and no drawing. So first thing's first, make your drawing! Now because we have a sphere inside a cube, you can see that the radius of the sphereis always half the length of any side of the cube (because a cube by definition has all equal sides). So $2r$ is the length of all the sides of the cube. Now plug $2r$ into your formula for finding the volume of a cube. You can either use the cube volume formula: $V = s^3$ = $(2r)^3 = 8r^3$ Or you can use the formula to find the volume of any rectangular solid: $V = lwh$ = $(2r)(2r)(2r) = 8r^3$ Either way, you getthe answer E,$8r^3$ Notice how answer B is $2r^3$. This is a trick answer designed to trap you. If you didn't use parentheses properly in your volume of a cube formula, you would have gotten $2r^3$. But if you understand that each side length is $2r$ and so that entire length must be cubed, then you will get the correct answer of $8r^3$. For the vast majority of inscribed solids questions, the radius (or diameter) of thecircle will be the key to solving the question.The radiusof the sphere will be equal to half the length of the side of a cube if the cube is inside the sphere (as in the question above). This means that the diameter of the sphere will be equal to one side of the cube, because the diameter is twice the radius.. But what happens when you have a sphere inside a cube? In this case, the diameter of the sphere actually becomes the diagonal of the cube. What is the maximum possible volume of acube, in cubic inches,thatcould be inscribed inside a sphere with a radius of 3 inches? A) $12âËÅ¡3$ (approximately $20.78$) B) $24âËÅ¡3$ (approximately $41.57$) C) $36âËÅ¡3$ (approximately $62.35$) D) $216$ E)$1728$ First, draw out your figure. You can see that, unlike when the sphere was inscribed in the cube, the side of thecube is not twice the radius of the circle because there are gaps between the cube's sides and the circumference of the sphere. The only straight line of the cube that touches two opposite sides of the sphere is the cube's diagonal. So we need the formula for the diagonal of a cube: $\sideâËÅ¡3 = \diagonal$ $sâËÅ¡3 = 6$ (Why is the diagonal 6? Because the radius of the sphere is 3, so $(3)(2) = 6$) $3s^2 = 36$ $s^2 = 12$ $s = âËÅ¡12$ $(âËÅ¡12)^3 = 12âËÅ¡12 = 24âËÅ¡3$ Though solid geometry may seem confusing at first,practice and attention to detail will have you navigating the way to the correct answer The Take-Aways The solid geometry questions on the SAT will alwaysask you about volume, surface area, or the distance between points on the figure. The way they make it tricky is by making you compare the elements of different figures or by making you take multiple steps per problem. But you can always break down any SAT question into smaller pieces. The Steps to Solvinga Solid Geometry Problem #1: Identify what the problem is asking you to find. Is the problem asking about cubes or spheres? Both? Are you being asked to find the volume or the surface area of a figure? Both? Make sure you understandwhich formulas you'll need and what elements of the geometric solid(s) you are dealing with. #2: Draw it out Draw a picture any time they describe a solid without providing you with a picture. This will often make it easier to see exactly what information you have and how you can use that information to find what the question is asking you to provide. #3: Use your formulas Once you've identified the formulas you'll need, it's often a simple matter of plugging in your given information. If you cannot remember your formulas (like the formula for a diagonal, for example), use alternative methods to come to the answer, like the pythagorean theorem. #4: Keep your information clear and double check your work Did you make sure to label your work? The makers of the test know that it's easy for students to get sloppy in a high-stress environment and they put in bait answers accordingly. So make sure thevolume for your cylinder and thevolume for your cube are labeled accordingly. And don't forget to give your answer a double-check if you have time! Does it make sense to say that a box with a height of 20 feet can fit inside a box with a volume of 15 cubic feet? Definitely not! Make sure all the elements of your answer and your work are in the right place before you finish. Follow the steps to solving your solid geometry problems andyou'll get that gold Solid geometry is often not as complex as it looks; it is simply flat geometry that has been taken into the third dimension. If you can understand how each of these shapes changes and relate to one another, youââ¬â¢ll be able to tackle this section of the SAT with greater ease than ever before. What's Next? Now that you've done your paces onsolid geometry, it might bea good idea to review all the math topics tested on the SAT to make sure you've got them nailed down tight. Want to get a perfect score?
