# How to Find the Area of a Hemisphere?

How to calculate the area of a hemisphere when radius is given?

## Hemisphere Area Calculation using Radius

Hemisphere is half of the Sphere which is the three dimensional object of a circle. The area of the hemisphere is half of the area of sphere.Let us learn here how to find the area of a hemisphere in this tutorial.

**Formula:**

**Area of a Hemisphere A = 2 x π x radius**^{2}

**Where,**

π (Pi) = 3.14 (constant)

Let us consider an example to find the area of a hemisphere whose radius is 5cm?

**Step 1:**

Given,

Radius = 5cm

Applying the values in the formula,

**A = 2 x π x radius**^{2}**A = 2 x 3.14 x 5**^{2}A = 2 x 3.14 x 25

A = 157 cm^{2}

**Result:**

Area of a Hemisphere,

**A = 157 cm**^{2}
