do the densities of the cylinder/wire have the same number of dig figs?

What densities? Can you give some context? Are you asking about a specific table of values?

if u round up the densities of the one that has more significant figures to have the same number of significant figures of the other, are they different?

Is "they" referring to the densities or the number of significant figures?
