find area between 2 circles: x^2+y^2=1 and x^2+y^2=4
using (x+y) da
I got the answer of (3*pi)/2 is this a correct answer? To check I just took the difference between the two circles and then got the half of that. Does this seem right?

Use polar coordinates.
When I integrate this, I got zero. It's possible I made a sign goof somewhere though.
