Hemisphere Calculator (Volume and Surface Area) by TheCalcTools

How the Hemisphere Calculator (Volume and Surface Area) works

A hemisphere is half a sphere: volume = (2/3)πr³, curved area = 2πr², and with the flat circular base the total surface is 3πr².

Bowls, domes and tank ends are often hemispheres; use the litre capacity for bowls measured in centimetres.

The formula

V = ⅔πr³; curved area = 2πr²; total = 3πr²

Worked example

Using the default values shown in the calculator:

Radius5
  1. Radius 5: volume 261.7994, total surface 235.6194.

Result:

Volume261.7994
Curved surface area157.0796
Total surface area (with the flat base)235.6194
Base area78.5398
Capacity in litres (if cm)0.2618

Frequently asked questions

How much does a hemispherical bowl hold?

A bowl with an inside radius of 10 cm holds about 2.09 litres.
