The main tank at an aquarium is a cylinder with diameter 203 ft and height 25 ft. Using 3.14 for pi, find the volume of the tank to the nearest cubic foot.

The radius is half the diameter: 203 ÷ 2 = 101.5 ft. The cylinder’s volume is 3.14 × 101.5² × 25 = 808,726.625 ft³, which rounds to 808,727 ft³. Choice B, 808,726 ft³, is the intended choice, though it is one cubic foot below the correctly rounded result.
