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.
