Grr... I posted this in the Mathcounts Problem Solving Thread at AoPS.
A rope is attached to a point at the bottom of a right circular cylinder. The rope is then wound around the cylinder four times before it is attached to a point at the top of the cylinder which is directly above the point where the rope is attached at the bottom. If the cylinder is 10 meters tall and has a radius of 3 meters, how long is the rope?

I don't bother checking that thread anymore. So many people complain and stuff.
Unrolling the rope says that the rope is the hypotenuse of a right triangle with height 10 and base . Pythagorean Theorem: . I think

From the Mathcounts website (problem of the week or go figure math challenge), OR http://www.yashar.biz/mathcounts/.
But I recommend making up your own (no logs, trig...)
