A drum has a circumference of 4 feet an is 6 feet deep how many gallons can it hold?

Answer 1

Let's start my noting that 1.0 cubic foot is equal to 7.4805 gallons.

Now lets determine the volume of the drum in cubic feet.

With a circumference of 4 feet, then the radius = 4/(2pi) = 0.63662 feet.

To determine the volume, we find the area of the drum cross section and then multiple by the height.

A = pi * r^2 = 3.1415 * 0.63662^2 = 1.273 square feet.

Then multiplying by the height, we get

V = 1.273 * 6 = 7.639 cubic feet.

Since 1.0 cubic foot is equal to 7.4805 gallons, the volume of the drum is

7.4805 * 7.639 = 57.1 gallons
