Find the volume of a right circular cone that has a height of 14.1ft and a base with a radius of 15.7ft. Round your answer to the nearest tenth of a cubic foot.
Q. Find the volume of a right circular cone that has a height of 14.1ft and a base with a radius of 15.7ft. Round your answer to the nearest tenth of a cubic foot.
Calculate Radius Squared: The formula to calculate the volume of a right circular cone is V=(31)πr2h, where r is the radius of the base and h is the height of the cone. We are given the radius r=15.7 ft and the height h=14.1 ft.
Multiply Radius Squared by Height: First, we square the radius: (15.7ft)2=246.49ft2.
Apply Cone Volume Formula: Next, we multiply the squared radius by the height: 246.49ft2×14.1ft=3475.409ft3.
Round to Nearest Tenth: Now, we multiply this result by 31 to apply the formula for the volume of a cone: (31)×3475.409ft3=1158.4697ft3.
Round to Nearest Tenth: Now, we multiply this result by 31 to apply the formula for the volume of a cone: (31)×3475.409 ft3=1158.4697 ft3.Finally, we round the result to the nearest tenth: 1158.4697 ft3≈1158.5 ft3.
