π has been the source of stability and continuation of mathematics since early days in life of human being. Where there is a circle and an are, there will inevitably be π, π is the main component of mathematics. π has been defined as the product of the circumference of a circle divided by its diameter. This definition is expressed in the form of π = C/D .
The relation π = C/D is a the cubic equation, solving of a cubic equation has been considered impossible. However, it is among the essential requirements of mankind to solve it. This problem has aroused mach effort of thinkers. Finding a solution to this equation is not a hobby. A measurement is always made to decide the two sides of a relation. Measurement of the circumstance and diameter of a circle with length measurement tools may not provide sufficiently precise results and hence it is not satisfactory.

All physical measurement made through the history have always given the value 3.15 for the length of circumference of a circle divided by the length of its diameter. You may make your own measurement to come to the aforesaid result. Physical testing has never proved the other way. This has been pointed at by many authors. Measurement and testing have been put aside because of the absence mathematical reasoning while their effects have been there. Inevitably a solution was adopted bused on scientific principles. It is said that Archimedes proved that any circle is equal to a right-angle triangle in which a side next to the right angle is of the same length as that of diameter of the sane circle and the other side of which next to the right angle has the same length as that of the circumference of the circle turned into straight line.
