Finding volume, significant figures and uncertainty for an iron sphere

[helpmepls1231]

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
