How many barrels of oil can fill a container 60 foot diameter X 40 high?

To determine how many barrels of oil can fill a container with a diameter of 60 feet and a height of 40 feet, we first calculate the volume of the cylinder using the formula ( V = \pi r^2 h ). The radius is 30 feet (half the diameter), so the volume is approximately ( V \approx 3.14 \times (30^2) \times 40 \approx 113,097 ) cubic feet. Since a standard oil barrel holds about 42 gallons, and there are 7.48 gallons in a cubic foot, the container can hold roughly 113,097 cubic feet × 7.48 gallons/cubic foot ÷ 42 gallons/barrel ≈ 19,000 barrels of oil.
