    Hey setanmuda.

    You will probably have to start by writing down a list of equations that relate all the variables in your picture.

    You have circles and right angled triangles [and quadrilaterals] which involve trigonometry.

    Try writing some of those down for us to get further comments.

    I get r = 2 by a rather complicated process ... looking for an easier method.
