Question

A cylindrical oil tank 8 ft deep holds 660 gallons when filled to capacity. How many gallons remain in the tank when the depth of oil is 5 1/2 ft.

Answer 1

5.5/8 = G/660= ratio of gallons to gallons is equal to the ratio of corresponding depth to depth

G = 5.5(660)/8 = 453.75 gallons when oil depth is 5.5 feet
