What is the formula for area of a half sphere?

Updated: 12/21/2022

The area of the curved space is given by (4 x pi x r2) / 2 = 2 x pi x r2

The area of the circle is equal to pi x r2.

Hence the area of the half sphere is 3 x pi x r2.

How do you figure out surface area for half sphere?

To do this question, we have to ask ourself, what formula do you use to find the surface area of a sphere. The answer should be known to you, but it is 4πr2. Since we know how to find the surface area for a full sphere, then finding the surface for a half sphere is just half the job. You use the formula for the full sphere 4πr2, and divide it by 2... so (4πr2) / 2 . Voila!
