Question

What is the radius of a circle if the area is 113.04 inches squared?

Answer 1

sub in your area and go backwards, 113.04= pi(r^2), then solve for r

Answer 2

The area of a circle is:

A = (pi) (r^2)
113.04 = (pi) (r^2)
r^2 = A/pi
r^2 = 113.04/pi pi is approximately = 3.14159
r^2 = 113.04/3.14159 now get the square root of both sides
r = 5.998 = 6 this is what the radius is approximately equal to
