The formula of the area of the circle is π r^2.
If the area of the circle is 13,266.5, we can plug it into the formula as follows:
13,266.5=π r^2
Now we may proceed to clear the variable by removing pi using opposite operation.
13,266.5/ 3.14 =r^2
4225= r^2 Clear the exponent by applying the radical to both sides.
sqrt (4225) = r
r=65
