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 r2 square units
where,'r' is radius of circle and π(Pi) is the mathematical constant with an approximate value of 3.14.
Find the area of circle if the radius is equal to 7 units.
Area of circle = π r2 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
- 7 units
- 15 units
