What is a hemisphere?

A hemisphere is half of a sphere—a 3D shape with a flat circular base and curved dome.

What formulas are used?

Volume = (2/3)πr³; curved (lateral) surface area = 2πr². Total surface (including base) = 3πr².

Calculate volume and curved surface area of a hemisphere from radius. Volume = (2/3)πr³, curved area = 2πr².
