The volume of a 100-foot diameter x 200-foot long cylinder is: 11,750,400 US gallons.
A 1.25-foot diameter by 525-foot long pipe will hold up to 4,819.5 US gallons of water.
A four-foot diameter pipe that is five feet long has a volume of 470 gallons.
Pipe is generally cylindrical and the dimension refers to the inside diameter. One cubic foot contains 7.48 gallons. The volume of a one foot long 20" diameter pipe is: pi(1.667/2)^2 = 2.18 cubic feet. At 7.48 gallons per cubic foot the total volume is 16.3 gallons.

Depends. Is the 1.5 inch measurement the ID (inside diameter) or the OD (outside diameter? And, how long is the hose?
A three-inch diameter pipe one foot long holds 0.367 gallon.
Approx 10.3 US gallons.
Do you mean a cylinder with a diameter of 5 feet and length of 12 feet? This would hold about 235.6 cubic feet or 1762.5 gallons
If the pipe is round, with a 55-foot diameter, and 36 inches long, then its capacity is 53,317.3 gallons. If the pipe is round, with a 36-inch diameter, and 55 feet long, then its capacity is 2,908.2 gallons. Either way, we have no way of knowing how much water is in it. For all we know, it may even be empty.
