Compute the surface area by rotating x=sqrt(2y-y^2) 0 <(or equal to) y <(or equal to) 1

I hope you are doing well

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .
