Need a custom math course? Visit http://www.MathHelp.com. This lesson covers the volume of a cone. Students learn that the formula for the volume of a cylinder is pi times radius squared times height, so the volume of a cylinder that has a radius of 10 feet and a height of 40 feet is pi times 10 squared times 40, or pi times 100 times 40, or 4000 pi cubic feet.
