Q: Obtain the area inside and outside

My first attempt was which I quickly realized has incorrect angles, since loops around twice as fast as the other graph. Thank you!

EDIT - I have just figured it out on my own! Sorry about that

You need two integrals.

The circle doesn't reach the second quadrant.

So you integrate from to with the bounds you used

BUT in the second integral you integrate from to

where the lower bound is zero not
