Homework Equations
equation of each circle (x-2)^2+y^2=9
(x+2)^2+y^2=9
The Attempt at a Solution
I solve for y for the circle (x-2)^2+y^2=9 then I took the integral of that from -1 to 0. I noticed that the shape looked symmetrical so I multiplied it by 4. But when I do it algebraically and using geometry I get a different answer then when I use the calculus.
