Question: 1 / 400

What is the fuel capacity (in gallons) for a tank sized 6 inches by 600 feet?

882

To determine the fuel capacity of a cylindrical tank, you can use the formula for the volume of a cylinder:

Volume = π × (radius)² × height

First, convert the dimensions given into compatible units. The tank has a diameter of 6 inches, so the radius will be half of that:

Radius = 6 inches / 2 = 3 inches

Next, convert the height to inches as well. Since the height is given in feet, you need to multiply by 12 to get inches:

Height = 600 feet × 12 inches/foot = 7200 inches

Now, substitute the radius and height into the formula:

Volume = π × (3 inches)² × 7200 inches

= π × 9 inches² × 7200 inches

= π × 64800 cubic inches

Using the approximate value for π (3.14) to compute the volume:

Volume ≈ 3.14 × 64800 cubic inches ≈ 203,901.6 cubic inches

To convert cubic inches to gallons, use the conversion factor, knowing there are 231 cubic inches in one gallon:

Volume in gallons = 203,901.6 cubic inches ÷
