Sorry for spamming everybody, but I keep getting the wrong answer and I don't know what I'm doing wrong, or if I'm even doing it right in the first place!

Find the area between a large loop and the enclosed small loop of the given curve.

r = 1 + 2cos(3θ)

aaaand this one:

Find the area of the region that lies inside both curves.

r = 6 + cos(θ)

r = 6 - cos(θ)

I love you for helping me!!!!
