# The shortest distance might go the long way round!

Geometry Level 4

You are given a ice cream cone with radius 1 m and slant length of 4 m (I know it's huge!) . You start winding a thread around the cone from a point on the rim of the cone in such a way so that you reach the starting point in the shortest distance.

If the shortest distance is $$x\sqrt { y }$$ for positive integers $$x$$ and $$y$$ with $$y$$ square-free, find the value of $$x+y$$.
