Question

Help me please!! thanks

Answer 1

Option (2)

Explanation:

Given:

Diameter of the circular base of a cone = 6 feet

Volume of the cone = 176 cubic feet

To Find:

Height of the cone

Solution:

Formula to be used to get the height of the cone,

Volume of cone =
`(1)/(3)\pi r^(2) h`

Here, r = Radius of the cone

h = Height of the cone

By substituting the values in the formula,

176 =
`(1)/(3)\pi ((6)/(2))^2(h)`

176 = 3πh

h =
`(176)/(3\pi )`

h =
`(176)/(3(3.14))`

h = 18.68 feet

Therefore, Option (2) is the correct option.
