How many barrels per foot are in a 16 ft Diameter Tank?

To calculate the volume of a cylindrical tank, you can use the formula ( V = \pi r^2 h ). For a 16 ft diameter tank, the radius ( r ) is 8 ft, and the height ( h ) is 16 ft. Thus, the volume is ( V = \pi (8^2)(16) \approx 4021.24 ) cubic feet. Since there are 7.48 gallons in a cubic foot and 1 barrel is 31.5 gallons, the number of barrels per foot is approximately ( \frac{4021.24 \times 7.48}{31.5} \approx 991.59 ) barrels per foot.
