Assume you have two circles with radius $n$, the radius between the centers of these two circles are $a$. Where $0.
Now remove the overlapping part between the two circles. Now let $B$ be the biggest triangle you can inscribe in the circles.
What is the ratio between the area of the circle sector and the triangle?
I actually gave this problem a shot. Here is my attempt at dealing with the specific case when $n=3$, $a=1$.
This gives out a ratio about 2.6. Now, I do not know if my drawing is 100% correct. Now how to actually show this in a easy way? After what I see one way would be to exploit the symmetry, and only look at the right side.
One could then assume the triangle has the greatest area when it is equilateral. Putting u a equation for the circle, then start messing with the intersection point between the top and the circle. Do anyone know a better way to do this problem ?
Also I am not able to perform the steps above, It is a tad too advanced for me. Hopefully someone is willing to help me!
