## How to Find the Area of Circle?

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

### Area of a circle = *π* r^{2 }square units

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

**Solved Example:**

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

**Solution:**

Area of circle = *π* r^{2} square units.

= 3.14× 7×7

= 153.86 square units.

∴ Area of circle = 153.86 square units. ^{ }

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

- 3 units
