A cylinder of radius r and height h is constructed inside a cone with base radius R10 in. and height of H -30 in., as shown in the figure. a) Create a polynomial expression for the vol- 9. ume V of the cylinder in terms ofr. b) Make a plot of V versus r: c) Determine r if the volume of the cvlinder is 800 in d) Determine the value of r that corresponds to the cylinder with the largest possible volume, and determine that volume
