Homework Help: Calculus Centers of Gravity

  1. Feb 25, 2010 #1
    (Moderator's note: thread moved from Calculus and Analysis)

    I just need to know if my answer is correct for the following:

    Find the z-coordinate of the center of gravity of the region:

    (x/(z^3-1))^2 + (y/(z^3+1))^2<=1, 0<=z<=1.

    I'm getting 7/16; am I in the ballpark? Thanks for any help.
