## Volume of a Cone

### Volume: Learn

Volume is the three-dimensional space within a solid shape. The units of volume are the cubes of the units of length (that is, if a shape's sides are measured in meters, then the shape's area is measured in cubic meters).

Cones and pyramids use the same basic volume formula of V = (1/3)*Base_Area*Height

For a cone, the base is a circle, so we can use the specific formula of V = (1/3)Πr2h

For example, the volume of a cone with height = 9m and radius = 4m is
V = (1/3)*3.14*42*9
= 3.14 * 48
= 150.72m3.
