Sphere Volume Calculator

Calculate the volume of a sphere (round shape), including its surface area and liquid capacity. If your bowl is a half sphere, you can halve these calculations for its approximate volume and area.

To calculate, enter the radius of the sphere, which is its diameter divided by 2.

Sphere Surface area Calculation

Surface area, the entire external surface area making up round ball, is calculated with the formula:

Area = 4 π r2

where r is the radius, and π (pi) is approximately 3.14.

Sphere Volume Calculation

Volume is how much liquid the sphere can hold. The formula to calcuate the volume of a sphere is:

Volume = 4/3 π r3

where r is the radius, and π (pi) is approximately 3.14

The result of calculating the sphere's volume is in cubic inches (or centimeters). Using the volume, the liquid capacity of the sphere is calculated in several common metrics (cups, ounces, milliliters, etc.)
