The radius, in inches, of the base of the cone will be:

r = 6 inches

Hence, option B is correct.

Step-by-step explanation:

Given

The Volume of a right circular cone V = 24 π cubic inches

The height of the cone h = 2 inches

To determine

The radius of the base of the cone r = ?

Using the formula involving Volume m, height h, and radius r of a right circular cone.

substituting V = 24 π, h = 2 to find the radius r

switch sides

simplify

Divide both sides by 2π

Thus,

As we know that the radius can not be negative.

Therefore, the radius, in inches, of the base of the cone will be:

Hence, option B is correct.
