Best ResponseYou've already chosen the best response.0I realize I am Integrating with respect to y since the semicircles are perpendicular to the yaxis. I found the intersection points to be from 2 to 2. Those are also the limits of integration. I am having trouble setting up the integral however.

Best ResponseYou've already chosen the best response.0Ohh I forgot to mention since I am integrating with respect to y the limits of integration are from 0 to 4 sorry.

Best ResponseYou've already chosen the best response.0Don't worry about it. :) . I almost have it but I wonder if I can change the "r" in the semicircle to an x in someway/
