A right cone has a base with a circumference of $16\pi$ inches and a height of 30 inches. The height of this cone is reduced while the circumference stays the same. The volume of the shorter cone is $192\pi$ cubic inches. What is the ratio of the shorter height to the original height? Express your answer as a common fraction.

V =Pi x r^2 x h/3

Circumference =Radius x 2 x pi

16 pi =Radius x 2 x pi
