We want to construct a cylindrical can whose volume is 105 mm}. The material for the wall of the can costs Sglnun", the material for the bottom of the can costs $7/m1n" and the material fbr the top of the (an costs $z/mm". Determine the dimensions of the can that will minimize the cost of the materials needed to construct the can. In order to receive Full credit, you must include the interval over which you are optimizing and test the endpoints of that interval
