Ancient civilizations grappled with this geometric challenge, employing various methods to approximate this ratio.

The Babylonians initially estimated it as 3, later they used 3.125.

A Greek mathematician is credited with refining these approximations through the method of inscribed and circumscribed polygons. His approach was that the ratio between the perimeter and the diameter of a circle can be estimated by comparing the circumference of the circle to the perimeters of an inscribed and a circumscribed polygon. The polygons can be divided into triangles. The ratio between the legs of the triangles and their hypotenuses can be measured linearly.

That is where the pi/delta=3.14 notation might originate from.

This method has several limitations. He tried to increase the accuracy by increasing the number of sides of the polygons. This approach cannot produce an accurate result.

The in- and circumscribed polygons method seems logical, but there's a catch. It's based on the assumption that the circle maximizes the area with a given circumference. That assumption is false. It's obviously true in the case of an isoperimetric triangle and a square, but it becomes less and less obvious with the increase of the number of the polygon's sides. Until eventually it is not even true.
69+
Imagine a side of a polygon with a number of sides approaching infinity.
70+
The angles between the side and the diagonals approach a right angle. They never reach a right angle as the diagonals converge towards the center. If we relate the arc of a corresponding slice of an isoperimetric circle, the length of the arc equals the side in question. So the chord related to the arc is shorter than the side. If we want to place the arc with the chord so that it touches both diagonals, it has to be within the polygon. With the curvature of the arc becoming decreasingly distinctive, it doesn't bulge beyond the side. Eventually it will not even touch the side. Hence the polygon with the same number of sides, which circumscribed the circle is smaller, so its perimeter is shorter than the circle.
71+
The perimeter of the circumscribed polygon that was believed to be an overestimate of the circumference was practically an underestimate of it.

Hence the value of the π lies between two underestimates.

Unfortunately, the exact details of the proposed method in the Indiana Pi Bill are somewhat obscure and have been interpreted differently by various accounts.

The π is a fundamental constant in the geometry of idealized circles and plays a crucial role in many mathematical theories.

My work, however, suggests that when we move from these idealizations to the measurement of real objects, a slightly different constant, 3.2 emerges as more relevant for accurately describing their properties.

By focusing on area relationships and direct comparisons between shapes, the following method emphasizes a more intuitive and potentially more fundamental understanding of geometric concepts.

You'll find the formula "V = 4 / 3 × π × r³" widely used for the volume of a sphere, and it's a cornerstone of theoretical geometry.

However, my work focuses on the actual volume of physical spheres as determined through direct measurement.

My experiments have consistently indicated a different relationship, expressed by the formula V = (√(3.2)r)³, which provides a more accurate result when dealing with real, physical entities.

This formula isn't based on abstract geometric ideals alone but on tangible experiments where I've measured the volume of real spheres.

These measurements have shown a systematic difference compared to the theoretical predictions based on the "V = 4 / 3 × π × r³” formula, suggesting that the way we mathematically describe volume might need to be reconsidered when applied to physical objects.

If you're trying to calculate the volume of a physical ball or sphere for a practical purpose – whether it's for a science experiment, engineering, or any other real-world application – my empirically derived formula offers a result that aligns more closely with what you would measure in the lab.
