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.

Rearrange the formula A = \pi r ^ ( 2) for r

tatyana61 [14]

Consider re-writing this formula as "A = pi*r^2." The backslash symbol "\" is unnecessary.

If A = pi*r^2, and we wish to solve for r, then divide both sides by pi:

A/pi = r^2

Taking the square root of both sides, sqrt(A/pi) = r (r must be positive in this situation).
