## Volume of a Sphere

### 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*).

We can calculate the volume of a sphere using a special formula.

V_{sphere}=(4/3)*Πr^{3}

For example, the volume of a sphere with
radius 3m is

V=(4/3)*Π*3^{3}

= (4/3)*3.14*27

= 3.14 * 36

= 113.04m^{3}.

Remember to convert any diameter measures into radius measures.
