Additional Formulas You Need for the ACT

To make up for not having the list of formulas provided for you, as on the SAT, ACT takers must memorize their math formulas. There are so many to know, but we attempt to give you a guide. Here are a few more formulas you are likely to use on your test.

Average Speed

To find the average speed, use the formula distance over time.

Rectangle Formulas

Area=lw l is the length and w is the width. Multiply them together to find the area of a rectangle. Perimeter=2l+2w Double the length of each side and add the results together to calculate the perimeter. Volume=lwh h is the height of the rectangle. Multiply length, width, and height to find the volume.

Triangle Formulas

Area=1/2(b*h) Think of a triangle as half of a rectangle, so you need to take half of the base time height. The base of the triangle is the length of a side. If you have a right triangle, the height is the length of the side with the 90 degree angle. If non-right triangle, drop a line from the apex of the triangle to the base. Isosceles triangles have two equal sides and two equal angles. If one of the angles is 90 degrees, the other two will be 45. The lengths of a right isosceles triangle are always xxx√2. The find the hypotenuse, simply multiply √2 by one of the sides. The side lengths of a right triangle with angles 30-60-90 can be found using the formula xx√3, and 2x. The smallest side, x, is opposite the smallest angle, 30. The longest side, 2x, is opposite the largest angle, 90.

Cylinder Volume

The volume of a cylinder is the area of the circle that makes up its end times the height of the cylinder.
