Question

A cone has a diameter of 3 inches the cone holds 12 cubic inches of water to the nearest in what is the height

Answer 1

5 inches

Explanation:

A cone's volume can be found using the formula
`V = (1)/(3) \pi r^2 h`. If the cone has a diameter of 3 inches then its radius is half r= 1.5 inches. Substitute r = 1.5 and V = 12 cubic inches.

`V = (1)/(3) \pi r^2 h \\12 = (1)/(3) \pi (1.5)^2 h \\12 = (1)/(3) \pi (2.25) h\\12 = 2.355h\\5.10 = h`

This means the height of the cone is 5.10 inches or to the nearest inch 5 inches.
