Question

Find the volume.
y= x^3
x = 1
y = 0
rotated about x=2
All I need is for someone to tell me how to get/what the larger radius is. I know the solid will end up looking like a washer once the function is rotated, and I know the small radius is equal to one. (Also, this is all done as a function of y, so the radius is perpendicular to the y axis)
