# Surface Area of Hemisphere Calculator

## How to use the Surface of Hemisphere Calculator

Calculating the area of a hemisphere is easy, just enter the total radius of the hemisphere, select the desire unit you measured the radius in and click the calculate button. Hence the surface area of the hemisphere has been calculated.

## Formula for Calculating Surface Area of Hemisphere

Hemisphere as indicated from its name is the half of a circular sphere. It is the circular sphere divided by its diameter, Th formula to calculate the sphere is 4πr² by the diving the sphere in two half than formula reduced to 2πr², now order to calculate the base area of the hemisphere we use πr² and add it the circular area of the hemisphere. The complete formula for measuring surface area of a hemisphere comes out to be **2πr²+πr²=3πr²**.

The formula to calculate the surface area of a hemisphere is:

*𝐴 = 2πr² + πr² = 3πr²*

Where:

- 𝐴 is the surface area of the hemisphere.
- 𝜋 is the mathematical constant pi (approximately equal to 3.14159).
- 𝑟 is the radius of the hemisphere.

## Result flexibility

we have designed the calculator in such that it will display the result in units from cm to km square so you don’t need to convert it to other units. we made it so simple.
