To find the diameter, we can derive the radius from the area. Then we can double it to find the diameter. Area = pi * r2 654 cm2 = pi * r2 654 / pi = r2 208.174665564 = r2 In order to isolate r, we have to take the square root of both sides. Another way to do this is to apply an exponent of 1/2. This cancels out on the right side, leaving a single r. 208.174665564(1/2) = (r2)(1/2) r = 14.428 cm diameter = 2*r = 28.8565
