Question

The area of the circle is 36 pi. What is the length of the diameter of the circle?

Answer 1

First, we have to find the radius.
$Area = \pi r^2$
If..
$r^2 = 36$
$r = 6$
To find the diameter, we multiply the radius by 2, so...
$6*2=12$
The length of the diameter of the circle is 12!

Have a nice day! :)
