25 POINTS ANDdont answer if u don't know it) Geologists have taken a collection of samples of a substance from a proposed mining site and must identify the substance. Each sample is roughly cylindrical, and the volume of each sample as a function of cylinder height (in centimeters) is V(h) = 1/4 πh^3. The mass (in grams) of each sample in terms of height can be modeled by M(h) = 1/4 h^3 − h2 + 5h. Write an expression that represents the density of the samples.
(Hint: D = M/V)

D(h) =
