# Math Help - finding area using curve integral

1. ## finding area using curve integral

using curve integral find the area on the positive y axes sides which is bounded by
$x^2+y^2=1$
$2y=1-x^2$
?
$\int_{c}Fdr$
what curve to choose here?
how to choose F?

2. ## Re: finding area using curve integral

Just find the area bounded by those two curves. Have you made a sketch? You should have something like a moon crescent.
