How to Find the Area of a Circle?

It is very easy to find the area of a circle with the given radius or diameter. The formula to calculate the area is pi X radius^2, where pi value is 3.14. For example: find the area of circle with diameter 8cm. First calculate radius, it is diameter / 2 = 8/2=4 cm. Now, Area of the circle = 3.14 X 4^2= 3.14 X 16 = 50.24 sq. cm.
