The key facts: 1 gallon is 231 cubic inches.
There are 12 inches in a foot.
The formula to use is v = Length * pi * r2
A conversion to gallons will be the last step.
v = (60 * 12) * 3.14 * 152
v = 720 * 3.14 * 225 = 508,680
v in gallons = 508,680 / 231 = about 2,200 gallons. Your instructor might want a more precise answer using a more accurate value of pi.

52,800 feet = 633,600 inches Volume = pi*122*633,600 = 286,633,887 cubic inches
A cylinder that has an 18-inch diameter and is 36 inches long has a volume of: 5.3 cubic feet.
The volume is approximately 0.3315 cubic feet.
Approx 246576 cubic inches.
803.84 is the volume in cubic ft when using 3.14 as pi.
We need to know the diameter AND the length of the cylinder to tell you the cubic volume.
16 cubic feet = 27,648 cubic inches
