Homework Help: Relative Uncertainty

  1. Oct 3, 2012 #1
    A copper cylinder has a mass of 56.09g with an uncertainty of +/- 0.01g, how do I find the absolute uncertainty and the relative uncertainty?

    An iron sphere has measurements:
    Height = 2.3cm +/- 0.05
    Diameter = 2.3cm +/- 0.05
    Mass = 66.69g +/- 0.01

    Find the volume with the correct unit, amount of significant figures and uncertainty
