How it works

Simply input the radius of the hemisphere into the calculator, and it will instantly compute the area using the formula mentioned above.

Definition of the Area of a Hemisphere:

The area of a hemisphere is the measure of the total surface space occupied by its curved surface and the circular base. It is given by the formula:Area = 2πr2where r is the radius of the hemisphere.

Solved Examples

Example 1

Radius: 5 cm

Area: cm²
A = 3π(5²) = 75π

Example 2

Radius: 8 meters

Area: m²
A = 3π(8²) = 192π

Example 3

Radius: 12 inches

Area: in²
A = 3π(12²) = 432π
