Question

Find the volume of a right circular cone that has a height of 8.1 in and a base with a diameter of 7.6 in. Round your answer to the nearest tenth of a cubic inch.

Answer 1

122.5

Explanation:

Answer 2

`V=122.5in^3`

Explanation:

The volume of a right circular cone can be found with the formula
`V=\pi r^2(h)/(3)` .

So, just plug in the values that are given (by the way, the radius is found by dividing the diameter by 2 since it's half the value of the diameter).

`V=\pi r^2(h)/(3)\\V=\pi (3.8)^2((8.1)/(3) )\\V=\pi (14.44)(2.7)\\V=122.484\\V=122.5in^3`
