    I think I can solve it, but I use a slightly different formula so I'm not sure you want me to bother...

    It's similar but has two pieces to it... http://tutorial.math.lamar.edu/Classes/CalcII/CenterOfMass.aspx

    You probably don't need my formula here because your object is symmetric, but I can't figure out how to use yours exactly

    Try considering the cone as a stack of discs. Then find the height of the disc where the volume above the height is the same as below. Hint: You need to use integration.

    hosein: Given that the density is constant throughout the object, it's really just a math problem.

    http://math.feld.cvut.cz/mt/txtd/5/txe3dc5i.htm this should help you. in this case r = h = 5 center of mass at 5/4 or 1.25 cm above base
