**Reiny**, Tuesday, May 8, 2012 at 7:20pmThe circumscribed circle would have a diameter equal to the diagonal of the square

each side of the square is 10 cm

using Pythagoras, the diagonal has a length of 10√2

so the radius is 5√2

area of circle = π(5√2)^2 = 50π

area of square = 100

difference = (50π - 100) cm^2 , (appr 57.1)
