    Exclamation Pappus theorem

    I have been given the curve y= ((x)^0.5)/4
    It is bounded by the line y=0 and x=1. and rotated around the x-axis.

    I found the volume to be pi/32 using pi x intergral y^2

    I have then been asked to check the volume using pappus theorem, but i don't know how to do that.

    Please Help!
