3.14159 = π …………… Is wrong and unacceptable. The right, correct and exact π value is 3.154700538.
We hereby declare our preparedness for a reasonable and reason-based discussion of the case, either in a meeting or through correspondence with all highly knowledgeable and reputable mathematicians and authorities in the world.
Our method is based on a well-established principle that relies on making rectilinear curved lines with a rule and compasses and working out the exact π value taking use of the lines inside the circle.

The Evident Principle :
Any half-plane arc or semi-circle is inscribed in an equilateral triangle. The length of semi-circle arc or π is exactly the same as that of each side of the circumscribed equilateral triangle.
The length of the curved line RT, a 270-degree line, is the same as and equivalent to the sum of lengths of the three segments LT+LR+GT.
38 Helpful Notes on preliminary issues
π is the product of circumference of a circle divided by its diameter
Circumference of a circle is 2 π radian. Radian is the length of a segment of circumference of circle that equals in length with the radius of the same circle. Radius is always supposed to measure a unit of length. Measurement is usually made between two objects of the same quality. Diameter is part of circumference of a circle made rectilinear. The equation given and the definition provided for π both imply that circumference and diameter of a circle are of the same quality. Circumference of a circle is considered to be π multiplied by its diameter. This implies that circumference of a circle has been considered to be a straight line. The diameter parts the circumference of the circle into two equal parts. Any 180-degree arc is called π. The length of any half-plane arc is the same as that of a straight segment. Any right-angle triangle is inscribed in a semi-circle. Only one right-angle triangle that has 45- degree acute angles is inscribed in a semi-circle and only two right-angle triangles with 30-degree and 60-degree acute angles are inscribed in a semi-circle. An equilateral triangle is formed as a result of the meeting made between each two out of three lines of the same length. An equilateral triangle may be named as a 3 π triangle. With two segments one of which measures twice the other, one may create any angle and specially a 60-degree angle. A theorem in geometry implies that in a right-angle triangle the acute angles of which are 30 and 60 degrees, the side opposite to the 30-degree angle is half the hypotenuse. The length of a 90-degree arc is half the length of half-plane arc. A 180-degree arc made rectilinear cannot be included in the related circle. With the rectilinear lines from the 90-degree and 180-degree arcs you may create hypotenuse and the right-angle side. The 180-degree arc made rectilinear can be made a fractured line to be included in its circle. This fractured line has always been and will be there in a circle. The 90-degree arc made rectilinear has also been and will be there in the circle in the form of a segment. Practical and objective geometry has a requirement for tools. Plain shapes form the basis of geometrics. The tools needed by and acceptable to geometrics are rule and compasses. Geometrics is the discipline of measurements. Reasoning is based on coincidence in the field of geometrics. Revolution is some kind of conversion or displacement and it is an issue of geometrics. Revolution can be realized with the help of a rule and compasses only. The shape of circle is the product of a revolution. Geometrics is the field of continuous quantity and it is independent of the field of discrete quantity. A discrete quantity may not be drawn. Concrete numbers are not considered as discrete quantities.
