Hemisphere Volume Calculator
Determine the volume of half a sphere accurately in seconds.
What is a Hemisphere?
Exactly half of a sphere.
A hemisphere is an exact half of a sphere. In geometry, if you cut a perfect sphere directly through its center, you create two equal hemispheres.
How to Find Hemisphere Volume
Calculating the volume of a hemisphere is like finding a sphere's volume and dividing by two.
Hemisphere Volume Formula
The standard equation for a hemisphere.
Where 'V' is volume, 'π' is pi, and 'r' is the radius of the hemisphere.

Frequently Asked Questions
How is a hemisphere's volume related to a sphere's?
The volume of a hemisphere is exactly half the volume of a sphere with the same radius.
What is an example of a hemisphere?
A dome×shaped bowl, an igloo, or the Northern half of the Earth are common examples of hemispheres.
Do I need the height of the hemisphere?
For a perfect hemisphere, the height is exactly equal to the radius, so you don't need a separate height measurement.
What if the shape isn't a perfect half-sphere?
If it's a piece of a sphere but not exactly half, it is called a spherical cap, and it requires a different formula.
