There is a circle with a diameter of 2. What is the exact average (not in decimal form, but in fraction) of all possible distances between 2 randomly chosen points in the circle?
You have a week. I suspect someone'll get it before then, but I don't know. It was difficult for me to solve.

I have no idea how to write it here
int_a^b f(x),dx
which would be equal to the area of a region in coordinate plane bounded by graph of f, the x-axis, and lines x = a and x = b, with areas below the x-axis being subtracted.
Does that help with notation?
