umm, it was a circle center (0,1) and the line was going through it on the LHS, so to figure out the right hand side of the circle i did .5pi r^2, which ended up being pi/2, cos radius is 1. then for LHS, i got equation for the top half of the circle by putting it in terms of y, found that area, with calculus then subtracted the area under the line.
final answer was 2.53 i think.....

i dunno if i got 2.53, it rings a bell though. so yeah, dunno if thats right, but thats how i approached it
