The **Radius of a Sphere from the Volume** calculator computes the radius (**r**) based on the volume of a sphere (**V**).

**INSTRUCTIONS:** Choose units and enter the following:

- (
**V**) Volume of Sphere.

**Sphere Radius (r):** The radius is returned in meters. However, this can be automatically converted to other length units (e.g. feet) via the pull-down menu.

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

If we solve for the radius (**r**), we have the formula in this calculator:

`r = ( 3/(4π)•V ) ^(1/3)`
