.
A circular wheel of radius r rolls, without slipping, through half a revolution.
The point X is on the horizontal diameter at the start.
The distance between the starting and finishing position of the point X is?
~~~~~~~~~~~~~~
As it is known, any diameter of a circle has 2 (two) endpoints.
Respectively, there are 2 different possible positions of the point X at the start, and, respectively,
two different final positions, giving two possible different answers.
So, if you want to get a unique answer, you must specify the initial condition in more accurate fashion.
