Volume of a cylinder = (pi) x (radius)2 x (length)
Radius = 1/2 diameter = 4.75 ft
Volume = (pi) x (4.75)2 x (19) = 1,346.76 cubic feet = 10,074.5 gallons (rounded)
The volume of a 100-foot diameter x 200-foot long cylinder is: 11,750,400 US gallons.
A four-foot diameter pipe that is five feet long has a volume of 470 gallons.
A three-inch diameter pipe one foot long holds 0.367 gallon.
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.
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.

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
Approx 10.3 US gallons.
To solve this we need to find the area of the tank in cubic feet, and then convert that to gallons. The volume of a cylinder can be found by multiplying the area of its base by its height. The area of a circle is equal to Pi×r2, where r is the radius of the circle. The radius is half of the diameter, so the area of the base of the tank if Pi×12, which equals Pi. Multiply this by 5 to find that the volume of the tank is 5 Pi cubic feet. Convert this to gallons to find that the volume is 117.5 gallons.
A 15-foot x 42-foot oval pool with an 8-foot deep end and a 3-foot shallow end will contain about 20,443 gallons of water.
aprox 400 gal i have a 4 ft dia tank that's 6 ft long it holds 200 gal
The radius of the pipe is 4.875 feet.The area of the cross-section ispi * r^2= 23.765625 * pi foot^2The volume per foot of length iscross-section * length= (23.765625 * pi foot^2) * 1 foot= 23.765625 * pi foot^3There are roughly 7.481 gallons/cubic foot, so one foot of length contains roughly(7.481 gallons/(foot^3)) * (23.765625 * pi foot^3)= 7.481 * 23.765625 * pi gallons= 558.55 gallons (not exact)So to contain 7500 gallons the tank must be7500 gallons / (558.55 gallons / foot)= 13.43 feet long (not exact)
