Question from kathy, a student:

How do you find the radius of a circle if the area is 803.84 and using 3.14 for pi.

Hi Kathy,

The area of a circle is given by

area = π r2

Hence if you know the area you can divide it by π to find the square of the radius. To find the radius take the square root.
