Question: Answer the question Find the radius r and height h of a cylindrical can of total surface area 140 cm whose volume is as large

Answer the question

Find the radius r and height h of a cylindrical can of total surface area 140 cm whose volume is as large as possible. (Express numbers in exact form. Use symbolic notation and fractions where needed.) = cm h. = cm Does there exist a cylinder of surface area 140 cm and minimal total volume? O Yes. Cylindrical cans of a given surface area have a minimal volume that must be greater than zero. No. Cylindrical cans must have a positive surface area and therefore must have some positive quantity representing its volume. It is impossible to determine what this positive value is. Yes. For cylindrical cans of a given surface area, the volume can become arbitrarily small
