The mathematical constant named pi is an artifact of a fundamentally flawed theoretical approximate. So are some other currently widely conventionally propagated formulas commonly referred to as Euclidean or specifically Archimedian. The CGS™ restores constructive geometry.

So, what the mathematical constant pi really stands for is the expression n×sin(180°/n)<pi<n×tan(180°/n). With n approaching infinity, that is 3.14... But that is not the true circumference to diameter ratio; it's just a failed approximate of it. ... nitter.gq/BasicGeometry/status/2…

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.

The arc intersects the sides of a concentric square at its quarters only if side/radius=4/√5, hence 3.2r² is the only true area balance ratio.

In the past few years I pinpointed several aspects of this. Or other aspects of the main point. There's no way to tell what comes from what. The relationships come as a whole. The point is that the mathematical constant pi is built on a series of flawed assumptions.

Figure - 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.
