With the limited resources that I had, I conducted some experiments.

The subject of the sphere experiment was a standard golf ball. That is not a perfect sphere because there are dimples on its surface. That can be compensated by calculating with a slightly shorter radius.

The measuring bottle had a nominal volume of 4 cl (40 ml ~ 1.3526 US ounce). That is not perfectly precise either because the nominal volume indicates the guaranteed amount of the fluid in it in commerce. They come with an air gap atop the fluid so the total capacity of the bottle is somewhat larger.

The second sphere experiment was done with the same ball and a nominal 5 ml syringe. The nominal volume of a syringe should be its real volume. I have measured its length and width to make sure and I found that its real volume is about 10% larger. I took that into account in the calculations.

Icould not provide the accuracy that the subject deserves, but the results aligned better with my V=(√(3.2)r)³ formula.
