Volume of a Sphere



r: radius
d: diameter

The volume of a sphere is given by:

V = 4 Π ∙ r3 / 3

Π defines the ratio of any circle's circumference to its diameter and is approximately equal to 3.141593, however the value 3.14 is often used.

Example: determine the volume of a sphere that is 4 meter in radius.

V = 4 Π ∙ r3 / 3 = 4 Π ∙ r3 / 3 = 4 ∙ 3.14 ∙ 43 / 3 = 267.947 m3
