Question

Find the volume of a right circular cone that has a height of 17.5 m and a base with a

circumference of 19.4 m. Round your answer to the nearest tenth of a cubic meter.

Answer 1

174

Explanation:

Answer 2

174.7 cubic meters

Explanation:

Formula:

V = (1/3)* π * r^2 * h

V = (1/3) * π * r^2 * 17.5

From knowing the circumference: 2*(π)*r = 19.4

r = 19.4 / (2*π)

V = (1/3)* π * (19.4 /(2π) )^2 * 17.5

V = (1/3) * (19.4)^2 * (1 / (4π)) * 17.5

V = (19.4^2 * 17.5 divided by (12π)

V = 6,586.3 / (12π)

V = 6,586.3 / 37.699111842‬

V = 174.7070336193518 cubic meters
