Area of a Circle

By: Haidyn Amato

This is the formula to find the area of a circle.

                                                      How to solve the area:

The capital A means area, then there is an equals sign. The first sign after the equals sign is the pi sign and pi is always 3.14. Then, you multiply 3.14 by the radius which is half way around the circle. But, radius has a 2 above it so you have to multiply the radius by itself because that means it is squared.  If there is a line that goes all the way across a circle you have to divide that number by two to get the radius. The answer to the area of a circle is always squared.

(pi always equals 3.14)

Example: how to find the area of a circle with a radius of 5m

A= pi x r2

A= 3.14 x 52

Example: find  the area of a circle with a radius of 2 in

A= pi x r2
