The volume of the cylinder is between 5 and 6 gallons.
A cylinder is a three-dimensional shape that is made up of a prism with a circular base.
Volume of a cylinder = nr^2h
Where:
22/7 x 28 x (15^2) = 19,800 cubic centimeters
First convert the volume to liters = 19,800 / 1000 = 19.8
Now convert to gallons = 19.8 / 3.785 = 5.23 gallons
