How to Use this Area of a Hemisphere Calculator?

To utilize the surface area of a hemisphere calculator, follow these steps:

Step 1: Input the radius value into the designated field.

Step 2: Tap on the “Calculate area” button.

Step 3: The calculator will then compute and display the surface area of the hemisphere in the output field.

Formula for Area of a Hemisphere

The surface area of a hemisphere consists of two parts: the curved surface area and the area of the base.

The formula for the total surface area of a hemisphere with a radius r is:

Total\:Surface\:Area=curved\left(lateral\right)\:surface\:area+area\:of\:the\:circular\:base\\

Total\:Surface\:Area=2\pi r^2+\pi r^2\\

Total\:Surface\:Area=3\pi r^2
