possibly in another reality, but, were pi a rational number, one could not construct a circle, let alone extend it to 3D. So a perfect sphere corresponds to nothing in this reality, pi being irrational.
There are only varying degrees of approximation, of what some perceive as perfection, so you all's argument boils down to "My approximation is better than yours"
I recommend you do a liver flush, filter out the globs or stones or whatever, measure each one, calculate a volume approximation for each glob, then do a summation using each of you all's methods of calculation.
As a final step, cram the globs into a graduated cylinder to get the real volume using the appropriate amount of pressure. Then can you know how far each approximation, calculated by you all's different methods falls short.
Then we'll know who is superior. Please document it with photos.
