Surface Area problem

  1. Mar 2, 2010 #1
    The problem statement, all variables and given/known data
    Find the surface area obtained by rotating the curve [tex]y = \frac{x^4}{16} + \frac{1}{2x^2}[/tex] 1 < x < 2 about the y-axis.



    The attempt at a solution

    My final answer is [tex]\frac{41\pi}{10}[/tex]. Is this correct?
