What is Pi?
Pi is is a symbol used in Mathematics. It is represented by the symbol π. It is a ratio of the Circumference of the Circle and the Diameter of the Circle. The value of Pi is an irrational number. Thus the exact value of the π is not found yet.
We can also define π as the total number of times the diameter is wrapped around the circumference of any circle. The approximate value of (π) pi is 3.14 or 22/7. The following illustration represents the value of pi and its relation with the circumference and diameter of the circle.
Value of Pi
The value of Pi is approximately equal to 3.14159. It is defined as the ratio of circumference of a circle to it’s diameter. If we divide the total circumference of circle with the diameter of circle, then it will always in ratio of 22/7. Pi is denoted by the Greek symbol π.
Its exact value is unknown and can not be calculated by the available means as it is an irrational number, i.e. non-recurring and non-terminating decimal. We define the π as the ratio of the circumference to the diameter of a circle. It is a constant used widely in every branch of Science and Mathematics.
Even if the size of circle is same, the value of Pi will always be same. Finding the exact decimal values of the π is tedious. The value of π up to a million decimal places is found using supercomputers and advanced algorithms. For general use and convenience the value of π in fractions is assumed to be 22/7 and in decimal is assumed to be 3.1415926 . . .
