In Exercise 71, if the diameter of the dish is halved and the depth stays the same, how far from the base of the smaller dish should the receiver be placed?

Data from Exercise 71

A satellite dish, like the one shown below, is in the shape of a parabolic surface. Signals coming from a satellite strike the surface of the dish and are reflected to the focus, where the receiver is located. The satellite dish shown has a diameter of 12 feet and a depth of 2 feet. How far from the base of the dish should the receiver be placed?
