Enter a value for all fields

The **Volume of a Spherical Shell** calculator computes the volume of a spherical shell with an outer radius and a thickness.

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

- (
**r**) Outer Radius of Sphere - (
**t**) Thickness of Shell

**Volume of a Spherical Shell (V):** The volume of the shell is returned in cubic meters. However the user can automatically convert the volume to other units (e.g. liters, gallons, or cubic inches) via the pull-down menu.

The Volume of a spherical shell can compute the amount of materials needed to coat any spherical object from a candy gumball to a submarine bathysphere.

The equation calculate the Volume of a Sphere is V = 4/3•π•r³. This formula computes the difference between two spheres to represent a spherical shell, and can be algebraically reduced as as follows:

**V = 4/3 • π • (r³ - (r-t)³)**

where:

- V is the volume of the spherical shell
- r is the outer radius and
- t is the thickness
