Area and volume formulas
Area measures the surface of a 2D shape, while volume measures the space inside a 3D shape. Circles and spheres use Ο (approximately 3.14159). Remember to use the same unit for all dimensions -- for example centimeters or meters -- so the result is in square or cubic units.
