I have two polar equations (circles) at r=8 sin(θ) and r=2. I want to find the area of the larger circle minus the area where they overlap. My approach was to find where the circles intersect by setting the two equations equal to each other giving: 8 sin(θ)=2, or (2,asin(1/4)) to set the boundaries for my integrals, but it doesn't seem to be putting me in the right direction (images of my work attached). Thanks!

That second screenshot shows 14+... when it ought to say 14pi+.
