Work out hemisphere volume instantly with clear inputs, formula shown and shareable results.
A hemisphere is half a sphere, so V = ⅔πr³. Its curved surface is 2πr² and adding the flat circular face πr² gives a total of 3πr².
Volume
V = ⅔πr³
Total surface
S = 2πr² + πr² = 3πr²
⅔π × 216 = 144π ≈ 452.389342 cubic units.
On the axis of symmetry, 3r/8 above the flat face.
