What is the Area of a Circle?

The formula for the area of a circle is A=pi X r^2, where A is the area of the circle, r is the radius of the circle and pi value is 3.14. For example, given: radius of a circle is 5cm , then the area of the circle will be 3.14 X 5^2 = 3.14 X 5 X 5 = 3.14 X 25 = 78.5 cm^2. Hope it is clear. You can find more information here:
