Re: arch problem!!

I can't recall sin law! Curse my useless psychology degree! :)
No time for a crash course at the moment. Anyone have the answer?

I have many arches and wish to create a circle. A single section of
the arch measures ( s =) 154.5 along the curve and (L = 150.5) from point to point.
If I connect many arches to form a circle, what will its diameter be?

HINT: If 2 th is circular segment angle, s = 2 R th ; L = 2 R sin(th)
; Eliminate th and from it solve numerically for R.
