I have to set the record straight regarding an important detail. It doesn't fit into a single post, so it will be a short thread. It's a recurring issue, that some claim that I claim "pi=3.2". That is false. It's the same with the Indiana Pi Bill. ...

3.2radius² is the exact area of a circle. From that 3.2diameter is the exact circumference. Confirmed via measurements. The wise insist that can't be, because their theoretical circumscribed polygon limits it to about 3.14. Their polygon is not as circumscribed as they think.

Don't fall for this type of fraud. The true volume of a sphere equals the cubic value of the square root of its cross-sectional area — just like a cube —, which is about a third larger than the result of this worthless, primitive, exaggerated approximate. Measure it.

The sphere’s true volume is revealed by what remains after the cones are removed. Every horizontal slice of the sphere is a disk of radius √(r² − z²). The cylinder with its double cone subtracted leaves an annulus of outer radius r and inner radius |z|. Both areas equal π(r² − z²). Cavalieri’s principle therefore equates the volumes. Subtract the two cones from the cylinder: 2πr³ − 2·(⅓πr³) = ⁴⁄₃πr³. The sphere occupies exactly two-thirds of its enclosing cylinder. Geometry finds equality in the slices we choose to compare.

This real-world example should make it clear why the pi is an artifact of a fundamentally flawed theoretical approximate. In case you missed the previous context: 3.2radius² is the exact area of a circle. The circumference can be derived from that algebraically as 6.4radius.

3.2radius² is the exact area of a circle (Fig. 1.); 6.4radius is the circumference (Fig. 2., pic.); the mathematical constant named pi is an artifact of a fundamentally flawed theoretical approximate (Fig. 3.).

Fig. 2. 6.4radius is the exact circumference of a circle derived algebraically by subtracting the area of a circle from a larger one and dividing the result by the difference of their radii which is the theoretical width of the circumference, denoted as x. C = 3.2(r² - (r - x)²) / x = 6.4r - 3.2x The width of the circumference is just theoretical. It separates the circumference from the rest of the circle. Its value may approach zero. That makes the value of 6.4r - 3.2x rather exactly 6.4r.

I'm not happy about it. It's not about changing the value of the pi; it's about replacing it by 3.2, since 3.2radius² is the exact area of a circle, 3.2diameter is the exact circumference, so the pi is an artifact of a fundamentally flawed theoretical approximate. Measure it.

It's not about changing the pi; it's about deprecating it, since it was introduced only because the result of a failed approximate of the circumference to diameter ratio is an infinite fraction who's digits can't all be written in equations, hence they needed a notation for it.

The worst part of the pi-propaganda is that they literally tricked folks into not trusting their own measurements. That is why I put so much effort into the explanations and the proofs. In fact, they are secondary. Measure twice. If you get 3.2, that is because that's what it is.

Gaál Sándor@gmac424730 Nov 2025

It was fun to work out the proofs and all that. But why was it necessary? Just wrap a piece of paper around something round, measure that piece of paper unwrapped and you will see that its length is 3.2 times the diameter. It's common sense. How could anyone prove otherwise?
