    The total formula for both surface areas of the circles and of the cylinder would be 2 x pi x r x r plus 2 x pi x r x h = 2 x pi x 9 x 9 (equals 509 to the nearest whole number) added to 2 x pi x 9 x 12 = 679 to the nearest whole number. adding both would give you 1188 ft squared to the nearest whole number(:

    They're not asking for the total surface area; they're asking for the surface area of the cylinder. In that case, it's only 2 x pi x 9 x 12 which would be 216ft 2
