Question

Here's a fun one to think about:
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?

Answer 1

both are of same length

Answer 2

because if u open up th circular tower with stair case on it like unfolding a sylindrical paprer we will get a rectangle with staircase as the diagonal of it,

and both rectangles will be identical
