    Volume

    I cant seem to get the same answer as the back of the book and waswondering ifsomeone could work it out so I see where i m going wrong.

    Find the volume generated by y=x^(1/2) rotated about y=2 between the origin and x=1.

    First draw a graph

    So the radius(distance between the graphs are)

    \pi \int_{0}^{1}(2-\sqrt{x})^2dx

    Can you finish from here
