What is the Sphere Volume?

Volume of a sphere

This formula is widely used in geometry applications. Understanding when and how to apply it helps you interpret calculator results correctly and catch input errors before they propagate.

Formula

V = (4/3) * pi * r^3

Substitute known values into the formula above. Ensure all variables use consistent units before calculating.

Worked Example

Radius 3 gives V about 113.1
