c. About 88 hours. The area of a circle is π(r)^2 which equals 1,809.56ft^2(substitute r with 24). You multiply that by 3.5 because the height is 3.5 and you get 6,333.46ft^3. You divide that by 1.2 and get 5,277.88, which is how many minutes it would take the pool to fill. You then divide by 60 because there are 60 minutes per hour and you get 87.9≈88. It would take 88 hours to fill this pool
