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)*Πr³

For example, the volume of a sphere with radius 3m is
V=(4/3)*Π*3³
= (4/3)*3.14*27
= 3.14 * 36
= 113.04m³.

Remember to convert any diameter measures into radius measures.
