Flashcard 15 - Next Generation Quantitative Reasoning, Algebra, and Statistics Flashcard Set for the ACCUPLACER Test

circumference of a circle: \(C = 2\pi r\)
area of a circle: \(A = \pi r^2\)

surface area of a sphere: \(SA = 4\pi r^2\)
volume of a sphere: \(V = \frac{4}{3}\pi r^3\), where r is the radius

Remember that distance is a 1-dimensional measurement, area is a 2-dimensional measurement, and volume is a 3-dimensional object.
