## What is Area of a Semi-Circle Calculator?

Cuemath's Area of Semi-Circle Calculator is an online tool that helps to calculate the area of a Semi-Circle with a given radius within a few seconds.

## How to Use the Area of a Semi-Circle Calculator?

Please follow the below steps to find the area of Semi-Circle:

**Step 1:**Enter the radius of the Semi-Circle in the given input box.**Step 2:**Click on the**"Calculate"**button to find the area.**Step 3:**Click on the**"Reset"**button to find the area for different values of the radius.

## How to Find the Area of Semi-Semi-Circle?

**Area of Semi-Semi-Circle** is defined as the amount of space enclosed within the boundary of a Semi-Circle.

** Area of a semi-Semi-Circle = ( π r^{2}) / 2 ^{ }square units**

where,**'r'** is radius of Semi-Circle and **π(Pi)** is the mathematical constant with an approximate value of **3.14**.

**Solved Example:**

Find the area of semi-circle if the radius is equal to 7 units.

**Solution:**

Area of semi-Semi-Circle = * (π r2) / 2.*

= (3.14× 7×7)/ 2 square units.

= 76.93 square units.

∴ Area of Semi-Circle = 76.93 square units. ^{ }

Similarly, you can try the calculator and find the area of semi-circle which has the following radius.

- 3 units
- 7 units
- 15 units
