Question
Find the volume of a right circular cone that has a height of 14.7 ft and a base with a circumference of 13 ft. Round your answer to the nearest tenth of a cubic foot.
Solution
Step 1: Find the radius of the base of the cone. The circumference of a circle is given by the formula C = 2πr, where r is the radius. So, we can solve for r:
13 ft = 2πr r = 13 ft / 2π ≈ 2.07 ft
Step 2: Find the volume of the cone. The volume V of a cone is given by the formula V = 1/3πr²h, where r is the radius of the base and h is the height. Substituting the values we have:
V = 1/3π(2.07 ft)²(14.7 ft) ≈ 100.6 cubic ft
So, the volume of the cone is approximately 100.6 cubic feet, rounded to the nearest tenth.
