Perhaps a refresher in real numbers would be useful.
Perhaps widdle this question down. Does pi exist?
The area of a circle is pi r^2. So, you can never really accurately figure out exactly what pi is so you really can’t figure out the area of a circle. But….. you can fill a circle and measure the area, no?
So, again, does pi exist even though you can’t completely tell anyone how much it is or even write it down. We are forever away from really knowing pi.
There are infinitely many numbers like pi. Perhaps these are useful fictions.
Does it matter?
It depends on your world view.
Consider it and get back to me. Or, ignore it and move on.
