3. Han finds an expression for S(r) that gives the surface area in square inches of any cylindrical can with a specific fixed volume, in terms of its radius r in inches. This is the graph Han gets if he allows r to take on any value between -1 and 5. a. What would be a more appropriate domain for Han to use instead? b. What is the approximate minimum surface area for the can?
