Question 4036
The area of a circle is given by:  A = (pi)(r^2)

The problem gives the area as:  1,808.64 sq. mi.

So,  (pi)(r^2) = 1,808.64      Solve for r.  Divide both sides by pi (3.14)
         r^2  = 1.808.64/3.14 
         r^2  = 576          Take the square root of both sides.
           r  = 24 Miles.
