Answer:

Option (2)

Step-by-step 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 = $\frac{1}{3}\pi r^{2} h$

Here, r = Radius of the cone

h = Height of the cone

By substituting the values in the formula,

176 = $\frac{1}{3}\pi (\frac{6}{2})^2(h)$

176 = 3πh

h = $\frac{176}{3\pi }$

h = $\frac{176}{3(3.14)}$

h = 18.68 feet

Therefore, Option (2) is the correct option.
