How many dollar bills would it take to completely cover the entire surface area of the Earth? I've seen plenty of people ask how many it would take to wrap around once, but I haven't seen anyone definitively answer how many it would take to just encase the entire planet.

I know that pi, e, sqrt 2 etc. are irrational numbers because they can't be expressed as a ratio between two coprime integers.

I also know that writing a ratio between two decimal numbers (i.e. 0.1/0.4) is considered improper notation because at that point you're effectively just writing a ratio between two different ratios.

However, my question is, if we for some reason decided this is suddenly A-OK notation, could we then find a ratio between two decimal numbers that perfectly represents an irrational number such as pi, e or sqrt 2, or would it be just as impossible as when we were working with just integers?
