Homework Help: Triple integral

  1. May 4, 2008 #1
    [SOLVED] Triple integral

    1. The problem statement, all variables and given/known data

    Calculate the triple integral of z when z [(r-1), sqrt(1-(r-2)^2)], r [1, 2], tetha [0, 2*pi]

    2. The attempt at a solution

    I've tried again and again, and I always get (17/4)*pi, while the answer is pi/2. Is there anything wrong with antiderivating in this order: dz, dr, d(tetha)?
