Two cylinders with the same volume but different radius, have the same surface area?
If not, how much is the difference between two 5mL cylinders with radius 10mm and 1mm?

If not, how much is the difference between two 5mL cylinders with radius 10mm and 1mm?What did your last slave die of?
Incidentally,
"What is the 3D shape with the maximum surface area?"
This sort of thing.

the top and bottom circle are the same, each having area:
where r is the radius of the cylinderand the outside is just
where h is the height of the cylinder

Of course, that only defers the problem, as the heat pipe needs a cold sink...
