That's not about physical sizes, but the accuracy needed. 3.14 is only
0.05% smaller than 3.1415926535897932384626433. That inaccuracy is
negligible in most applications. For more precision, 3.1416 is only
0.0002% larger. 355/113 is off by 0.000008%.
Yes, memorizing pi to so many digits is just a mental exercise, not
for practical use.
