Find the volume of a right circular cone that has a height of 13.8 ft and a base with a radius of 7.8 ft. Round your answer to the nearest tenth of a cubic foot.
The formula for the volume of a cone is V = (1/3)πr^2h, where r is the radius of the base and h is the height of the cone.
Plugging in the values given:
V = (1/3)π(7.8)^2(13.8)
V ≈ 1/3 * 3.1416 * 60.84 * 13.8
V ≈ 1/3 * 190.85328
V ≈ 63.61776
Rounded to the nearest tenth, the volume of the cone is approximately 63.6 cubic feet.
