6650 is X to 3sf, where 6645 <= X < 6655
6650 is Y to 4sf, where 6649.5 <= Y < 6650.5
It could be either. What is the context?
Without any further qualification it would be 3sig.fig.

No.
How many sig figs is 1000000? One, not seven.

My teacher called it a place-holder.
it depends on the context, can be either.
6650 by itself with no further qualification is accurate to 3 sig.fig.
IF it was accurate to 4 sig.fig. you would need to say "6650 (4 sig.fig.)"
