It’s close enough that you won’t find any difference when using it in any practical sense. However… How do you construct 355/113 practically?
No, if you want to do anything with a circle practically, you use the radius or diameter. That’s how it’s constructed.
In the rare case you’d like to know what the circumference or area of a circle is, your won’t find the fence or paint in those specific sizes anyway, so the rounding is not by decimals, but by arbitrary lengths of fence or buckets of paint.

Wonderful response!
But… how many circular bananas does it take to make a single straight banana?
