if we unravel the cylinder out, we can easily determine its length since we know its area is 1250phi meter squared. Therefore, its length is 1250phi/50= 25phi. Note: phi is not pi... Since we know the length, we can also easily calculate the radius of the circle since we know the perimeter of the circle= length of the unravel cylinder. Perimeter= 2pi* radius= 25phi Therefore, radius= 25phi/2pi If you want to simplify it further, then radius= (25 1.618033..)/( 2* 3.141159) =40.4508/6.2823=6.4388...
