This question seems too easy to post in the meta-math section, so I figured I'd try it out here:
Two circular towers are the same height but have different diameters. A spiral staircase runs around each of the towers from top to bottom. The slopes of the staircases are identical and constant. Which staircase is longer?

Question

say slope is 1, diams are 1 and 2, height = 50 for good measure :)
