## 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)Πr^{2}h

For example, the volume of a cone with height = 9m and
radius = 4m is

V = (1/3)*3.14*4^{2}*9

= 3.14 * 48

= 150.72m^{3}.

### Volume: Practice
