many students are blown away by the fact that every digital sat math section has a geometry cheat sheet at the very beginning<\/strong> (hopefully, they pick up on this before they take the actual test). <\/p>\n

math formulas provided for you on the sat formula reference sheet<\/h2>\n

here are all the math formulas that will be provided for you for reference on the digital sat with more details on the most important ones below:<\/p>\n

\"math<\/p>\n

1. circumference and area of a circle<\/h3>\n

recall this formula as naturally as you can recall your home address. it\u2019s easy:<\/p>\n

area = \u03c0r^2<\/p>\n

circumference = 2\u03c0r<\/p>\n

and don\u2019t mix the two up!<\/p>\n

2. area of a rectangle<\/h3>\n

this one should be pretty intuitive. to find the area of a rectangle\/square multiply length x width (they are the same in a square). perimeter, which is not part of the sat cheat sheet, is found by adding the length and width and multiplying by 2.<\/p>\n

3. area of a triangle<\/h3>\n

it\u2019s 1\/2 of the base x the height. don\u2019t waste time flipping the pages back and forth. know this cold.<\/p>\n

4. volume of a box<\/h3>\n

don\u2019t memorize this\u2014just refer back to the page if necessary. one thing you don\u2019t get is the surface area of a box. for a cube, things are much easier: volume is s^3, in which s = the side; surface area is 6s^2.<\/p>\n

5. cylinder<\/h3>\n

you probably won\u2019t see a problem relating to a cylinder. anyhow, it\u2019s not that easy to memorize. so it\u2019s great to see it as part of the cheat sheet at the beginning of each section.<\/p>\n

6. pythagorean theorem<\/h3>\n

know this cold. and be fluent and being able to find the missing sides.<\/p>\n

7. 30:60:90 triangle<\/h3>\n

don\u2019t feel you have to know this cold, though it will make things faster. just make sure you know what everything stands for when you refer to the diagram.<\/p>\n

8. 45:45:90<\/h3>\n

as a tutor, i always want to make sure my students know this well. but at the end of the day, if you don\u2019t know memorize the formula, you can just use the cheat sheet. just make sure you know how the sides are connected.<\/p>\n

for instance, sometimes you can have a \u221a2 as one of the sides. the relationship between the two equal sides and the hypotenuse is that the hypotenuse will always be \u221a2 times greater.<\/p>\n","protected":false},"excerpt":{"rendered":"
