Answer:

7 inches

Explanation:

Given

Shape: Cone


Volume = 84\pi in^3


Radius = 6in

Required

Determine the height

Volume of a cone is:


V = (1)/(3)\pi r^2h

Substitute values for volume and radius


84\pi = (1)/(3)\pi * 6^2 * h


84\pi = (1)/(3)\pi * 36 * h


84\pi = (36)/(3)\pi* h


84\pi = 12\pi* h

Solve for h


h = (84\pi)/(12\pi)


h = 7

Hence:

The height is 7 inches
