Best ResponseYou've already chosen the best response.1If you visualize the graph of y (where y=0 and x=2 are boundaries), you will see that its domain is in the first quadrant from y = 0 to 4. We need it in terms of y if we want to use the disc method, so x = sqrt{y}. Therefore integrate \[\pi \int\limits_{0}^{4}(\sqrt{y})dy\]
