Guys, could you give a couple of hints about 8.23 B? I cant find intersection of the areas in the rectangle.

Try doing something similar to what we did with 8.6. If you add the areas of the two quarter circles, you'd be adding some of the shaded region twice, but that can be fixed by subtracting the area of another region.
