What is the Sphere Volume Calculator?

This calculator finds a sphere's volume (the space it occupies) and surface area from its radius.

How to use it

  1. 1 Enter the radius.

Worked examples

Frequently asked questions

Why do volume and surface area look similar at radius 3?

It's a coincidence of this specific radius (3) — volume and surface area scale differently (r³ vs r²) and generally diverge at other radii.
