Question

A cylindrical oil tank holds 510 gallons when it is filled to its full
height of 8.0 ft. When it contains oil to a height of 3 ft 9 in, how
many gallons are in the tank?
298.2 gal
302.4 gal
277.9 gal

239.1 gal

Answer 1

Answer:

Step-by-step explanation:

8 ft = (12 * 8) = 96 inches

3 ft 9 in = (12 * 3) + 9 = 45 inches

510 gallons to 96 inches = x gallons to 45 inches

510 / 96 = x / 45....cross multiply because this is a proportion

(96)(x) = (510)(45)

96x = 22950

x = 22950 / 96

x = 239.0625 rounds to 239.1 gallons <===
