Homework Help: Center of mass of a half-ball

  1. Nov 12, 2006 #1
    Hi, I've been working on the following question for a little while. I've looked it over several times and I can't find any obvious (to me anyway) errors in my work. Would you please scan it through and let me know if I am correct or, if not, please guide me in the right direction so I can try again.

    I have attached a scanned copy of the question and my work.

    Thank you in advance,
    -Zachary Lindsey

    I don't see anything wrong with it.

    (Except that you really don't need to integrate to find the volume of the hemisphere: it is (1/2)(4[itex]\pi[/itex])!)
