Related Rates: Conical Container

[KHelton14]

I can't figure out what I already have and what I need to find.

An inverted conical container has a diameter of 42 in and a depth of 15 in. If water is flowing out of the vertex of the container at a rate of 35pi in^3/sec, how fast is the depth of the waterdropping when the height is 5 inches?

Does this mean that you are not familiar with terms like "inverted", "diameter", "depth", "flowing...at a rate of", and "height"? :shock:
