## How to find the surface area of a hemisphere

The surface area of a hemisphere is 3*pi*r^2, where r is the radius of the hemisphere. The radius is the distance from the center of a sphere to its edge. For example, if you have a ball with a radius of 1 meter (1 m), then its surface area would be 6.28 square meters. If you want to find out how many squares fit onto this sphere, multiply 6.28 by itself! That will give you more than 5 million square meters; not bad for such a small ball!

To calculate hemisphere surface area using this formula:

- Convert pi into decimal form (3.14)
- Multiply it by half your original radius squared

## What’s the area of a hemisphere formula?

The surface area of a hemisphere is the area of a circle with a radius equal to the diameter of the sphere. The formula for finding this is:

A \text { (of a hemisphere)} = \frac {A \text { (of a sphere)}} {2}## FAQ

### What is a hemisphere?

A hemisphere is a 3D figure which is obtained by cutting a sphere into two equal halves through its diameter.

### What is a hemispherical shell?

In geometry, a spherical shell is a generalization of an annulus to three dimensions. It is the region of a ball between two concentric spheres of differing radii.
