Circles and Pie

Okay not Pie, Pi!

Hi I'm Will and I'm going to show teach you about finding the area of a circle.
Here's the formula: or in words, Area equals pi times radius squared

Let's say the radius of a circle is 3 cm.
First multiply the radius by the radius. 3 x 3 =9
Then multiply this answer by 3.14 (the short version of pi). 9 x 3.14 = 28.26 cm.
So your answer is the area of a circle with a radius of 3 cm is 28.26 cm.

Here's some words to rememember when you are solving the area of a circle:
Pi is 3.141592... when solving math problems we use 3.14
Formula- a way of finding the perimeter, area, etc.
Radius- line from the center point of a circle to a point on the outside of the circle

Now makes some example of your own, and share them with us by leaving them in a comment below.

Thanks!
