The **Volume of a Sphere from the Circumference** calculator computes the volume of a sphere based on its circumference (c). * Geometric Sphere* **INSTRUCTIONS:** Choose your length units (e.g. feet or meters) and enter the following:

- (
**c**) The circumference of the sphere.

**Volume:** The Volume of the Sphere (**v**) is returned in cubic meters. However, this can be automatically converted to numerous other volume unites (e.g. cubic feet, gallons and barrels) via the pull-down menu.

The equation for the volume of a sphere is as follows:

V = ^{4}/_{3} π r^{3}

This calculator replaces the radius with C/(2 π), based on the formula for the circumference of a circle c = 2 π r.

The volume of a sphere is a special case of the Volume of an Ellipsoid (CLICK HERE) where the three semi-axes (a, b, c) are all the same and equal to the radius (r)

One can see that they are algebraically the same when a,b,c are all equal to one value (r).
