calculus – Area of region inside circle and Lemniscate?

What is the area of the region inside the circle $r=1$ and inside the lemniscate $r^2=2cos(2(theta))$?

I can’t quite figure this one out. I was able to graph it easily and find the circle is one all the way around and the Lemniscate has tip petals on the x axis. How would you find the area if it is asking inside both figures?
