6. Gravel is being dumped from a conveyor belt at a rate of 8 cubic feet per minute. It
forms a pile in the shape of a right circular cone whose base diameter and height are
always the same. How fast is the height of the pile increasing when the pile is 20 feet
high?
Transcribed Image Text:Decide if each of the following problems is a linearization problem, an optimization prob-
lem, a related rates problem, a graphing problem, or a Newton's method problem.
Identify. Label the problem as one of the five types or explain that it is not exactly one of
those types (and how you know).
Begin solution. For each problem, start the solution.
