    you take a curve, you revolve it around x axis or y axis, and you get a surface. no biggie

    Q2. what is the equation of the resulting ellipsoid surface generated by revolving x^2 + x ^(2/9) = 1 around the z-axis ?

    x^2 + x ^(2/9) = 1 can be simplified to be a straight line (no z dependence) so x= something |dw:1319456124573:dw|

    the solid of revolution will just be a cylinder with something as the radius |dw:1319456244500:dw|
