# Determine the area common to r= 3+3sintheta and r=3

The instruction says the answer must be in Exact form.

Determine the area common to r= 3 + 3sintheta and r= 3

when I graphed this it is a cardioid and a circle, I am having hard time starting to solve for this because when i try to fin the intersection using r1+r2 it givesss weird results

our topic right now is about polar curves and polar regions.

thank you so much

I mean under the "x axis" of this graph the radius r is 0<r<3 since it is always positive and only based off of angle in radians!!
