So to start off, I already graphed the system of inequalities on the set of axes, I as well found the coordinates of the points of intersection algebraically. But I am now at a loss, I do not understand how to do the following problems, I'm a little rusty on Chords(I believe thats what this is called) so any help is appreciated. In any case, here is the problem:
Graph the following system of inequalities on the same set of axes:
Now I just need to do the following:
Calculate the length of arc AB
Calculate the area of the shaded region
However I do not know how, and as I stated earlier any help is appreciated, please and thank you!
