FAQ

What is the sphere volume formula?

Volume = (4/3)πr³, where r is the radius of the sphere.

Why is the formula different from circles?

Volume involves three dimensions (r³), while area involves two. The 4/3 factor comes from calculus integration.

How does volume change with radius?

Volume scales with r³. Doubling the radius gives 8 times the volume!

What about hemispheres?

Hemisphere volume = (2/3)πr³, exactly half of a full sphere.
