I've drawn up a basic diagram of how this looks below...

I know that h = 2R^2/R-r, but previously in the other question I used the angles and numbers and the laws of sine and cosine to get the answer. So, I'm a bit stumped on what to do next.

Any thoughts or comments would be greatly appreciated.
