Jeannie wishes to construct a cylinder closed at both ends. The figure at right shows the graph of a cubic polynomial function, V, used to model the volume of the cylinder as a function of the radius if the cylinder is constructed using 150

What are the zeros of the function V?

What are the zeros of the function V?

What is the relative maximum value of V, and where does it occur?

The equation of this function is V(r) = c(r3 − 72.25r) for some real number c. Find the value of c so that this formula fits the graph.

Use the graph to estimate the volume of the cylinder with r = 2 cm.

Use your formula for V to find the volume of the cylinder when r = 2 cm. How close is the value from the formula to the value on the graph?
