I'm working on corrections for a test and would please like some help. Please excuse my attempts at solving it.

Problem Six

Problem Six (7 pts) In the gure above, the shaded region bounded by arcs of circles with radius r and R is called a. lune. Note, the smaller circle can be described by the equation :32 + (y H)2 = r2 and the larger one by m2 + y2 = R2. 1. (3 pts) Show that the small and large circles intersect at the points 2. (4 pts) Find, but do not evaluate, an integral for the area of the lune. What trignometric substitution would you use to evaluate your integral? is A 3 W/ (r71 R7935 Scanned with CamScanner
