# mean distance between three point

Mathematics Asked by Yaniv765 on August 6, 2020

I have a question that I would like your help solving.

Let say I have three different points $$a,b,c$$ and a radius $$r$$.

Let say the $$A,B,C$$ are the circles with the centers $$a,b,c$$ respectively and with radius $$r$$.
Now, I know that the point $$b$$ lays in the circle $$A$$, and the point $$c$$ lies in the circle $$B$$ but not $$A$$ (meaning that $$c$$ is in the lune created by circles $$A$$ and $$B$$, $$c$$ is in $$Bsetminus A$$).
I want to calculate the mean distance between points $$a$$ and $$c$$.
