Question

The farm where you just started working has a vertical cylindrical oil tank that is 2.5 feet across on the inside. The depth of the oil in the tank is 2 feet. If 1 cubic foot of space holds 7.48 gallons, about how many gallons of oil are left in the tank?

Answer 1

The answer is 73. 4 gallons im 100 percent

Answer 2

Answer: 73.4 gallons

Explanation: We know that the tank has 2.5 feet across on the inside, so the diameter is 2.5 feet, this means that the radius us 1.25 ft (because diameter = 2*radius)

Now, the volume of fluid inside the tank is:

V = pi*radius^2*height

Where pi = 3.14

radius = 1.25ft

height = 2ft

V = 1.25^2*2*3.14 = 9.81 ft^2

Now, for each ft^2 we have 7.48 gallons, so we have:

9.81*7.48 = 73.4 gallons of oil
