Math Help: Area of circles

Refresh your competency in the various areas of Mathematics.

AREA OF CIRCLES

In this module, you can study what the area of a circle is and how to find the area of a circle if you know its diameter or radius.

 

Did you know?

If a circle and a square have the same perimeter, their areas will be different.

Pi times r-squared means Pi x radius x radius.  It does NOT mean Pi x radius x 2.
