Regardless of your opinion on sig figs, '4' is one sig fig & '1200' is two. Its comparision to propagation of error is an entirely different discussion. It is clear in this discussion the numbers are not exact (infinite sig figs). The reason it is clear the number has one or two sig figs and is not an exact number is it is stated as such.
That said, yup. If they were exact (like 2*r*pi), it's a different discussion. Just as this is a derail on the parent discussion.
