Volume of a Hemisphere Calculator
Find the volume of a hemisphere from its radius.
A hemisphere is half a sphere; its volume is half a sphere's volume.
The math behind it
V = (2/3)πr³, exactly half of the full sphere's (4/3)πr³.
Worked example
Radius 6 → V = (2/3)π(216) ≈ 452.39.
FAQ
How does this compare to a cone of the same radius and height?
A hemisphere holds twice the volume of a cone with height equal to its radius.
