It is not possible to answer the question because you have not stated which of the two given measures is the height and whether the other measure is the radius or diameter or circumference. Without these critical items of information it is impossible to give a sensible answer.
141 gallons of water.
Convert everything to feet, then use the formula for the volume of a cylinder. Since the answer will be in cubic feet, you'll then have to convert it to gallons.
