#0, area between 3 circles
Posted by tiusic on Nov-10-06 at 09:25 PM
I came across this very interesting puzzle earlier today and after a little work, I think I have the answer (but it was an open question with no given answer so i can't check).
Find the formula for the shaded area in the picture below from the circles' radii of a, b, c.
