Homework Help: Volume integral with 3 formulas mmn 15 3a

  1. Jun 25, 2011 #1
    find the volume inclosed by z=0 x=y and y^2+z^2=x
    ??

    i am having trouble drawing it
    i know i should look on th shadow of it on the x-y plane and integrate by it

    i can project on every plane i want to and build the integral appropriatly
    i jast cant imagine this shape

    if i can find out how the shape looks like
    then it will solve it very fast
    but imaganening a parabaloid cutting x=0 plane and z=0
    is very hard thing to draw and imagine

    Tell us what you get when you project onto each plane?
