Dear all,

I feel this should be a simple problem but I can't solve it. Could you give me a hand?

Imagine if an arc is bounded by a rectangle of dimensions width and height. The arc starts in the bottom left corner of the rectangle, and ends in the bottom right corner. The apex of the arc is the center of the top side of the rectangle. A picture of this is shown half way down this page:

Assuming that the arc is less than a semi circle, if I know the length of the arc and the height of the rectangle, how can I calculate it's width?

Any help gratefully received,

kenneth
