2. A cylindrical can is to have a volume of 20 cm³. Find the radius and height of the can that will minimize the amount of material to be used. hint: to find the surface area of a cylinder, you add the top and bottom areas (which are both circles) and the lateral surface area (which is the circumference times the height).
