Find area of a circle? - Answers

To find the area of a circle you must know the radius or diameter. The diameter is 2x the radius so the radius is 1/2 the diameter. For example, if the diameter is 6, the radius is 3. Next you must square the radius. For our instance, 3 squared is 9. ( 3x3=9) Now you must multiply the squared radius by pi.9 x 3.14= 28.26. (3.14 because it is pi rounded) The area of the circle with a radius of 3 is 28.26. We rounded pi to get 3.14. The formula is A=Pi r2.
