Find the volume of the region between y=2x and y=x^2 when rotated about y=4 using the washer method

In this problem, we rotate around the axis y=4 instead of the x or y axis. This complicates our setup just a bit and makes for a pretty good calculus 1 or calculus 2 problem!.

if xy=2, rotate about y=-x from x=√2 to 2 find volume

can i not just translate upwards, and then rotate it?
