Question

Find the volume of a right circular cone that has a height of 9.5 inches and a base with a circumference of 3.4 inches round your answer to the nearest 10th of a cubic

Answer 1

Answer:
`28.8 in^(3)`

Explanation:

`V=\pi r^2(h)/(3) \\V=\pi1.511971959^2(9.5)/(3) \\V=\pi7.239187482\\V=22.74257821\\=22.7 in^3`

(for the equation radius is needed but you have the circumference so to find the radius from the circumference, you need to do
`(circumference)/(2\pi )` and that's how you get 1.511971959)

Hope this helps!
