How much water is in a pipe 1/2 mile long?

The length of the pipe (h) is 1/2 mile, which is 2640 feet.

To calculate the volume of water in the pipe, we can use the formula for the volume of a cylinder: V = π * r^2 * h, where r is the radius of the pipe and h is its length.

Given that the diameter of the pipe is 8 inches, the radius (r) is 4 inches (8 inches / 2). Converting inches to feet, r = 1/3 feet.

The length of the pipe (h) is 1/2 mile, which is 2640 feet.

Using these values, we can calculate the volume (V) in cubic feet: V = π * (1/3)^2 * 2640 ≈ 2925.82 cubic feet.

To convert cubic feet to gallons, keep in mind that 1 cubic foot is approximately 7.48 gallons. Therefore: Volume in gallons = 2925.82 * 7.48 ≈ 21858.41 gallons.

So, there are approximately 21,858.41 gallons of water in a pipe that is 1/2 mile long and 8 inches in diameter.
