PROBLEM 13 : Consider a rectangle of perimeter 12 inches. Form a cylinder by revolving this rectangle about one of its edges. What dimensions of the rectangle will result in a cylinder of maximum volume ?

Question

anonymous · Answer

Isn't it infinite because the volume of a cylinder is $$\pi*r ^{2}h$$So when you plug in 2 for r you will have$$4\pi*h$$ which is a linear a equation which doesn't have a maximum. If I'm wrong sorry. Its been awhile.
