a 9x12 rectangle has diagonals of d = square root of(9^2 + 12^2) = square root of 225 = 15 since these diagonals are also the diameter off the circle A = pi (d/2)^2 = pi (15/2)^2 = 176.7 C = pi times d = pi(15) = 47.123
a 9x12 rectangle has diagonals of d = �ã(9^2 + 12^2) = �ã225 = 15 since these diagonals are also the diameter off the circle A = ƒÎ (d/2)^2 = ƒÎ (15/2)^2 = 176.7 C = ƒÎd = ƒÎ(15) = 47.123
