Greek letter pi123 (used 1st time by William jones in 1706) is an irrational number. Because of its decimal part that is nonrepeating and nonterminating.
Pi123
Pi symbol  π 
Pi Value  22/7 
Pi in decimal  3.14 
π is the ratio of circumference of a circle to the diameter of that circle. That ratio is same for every size of circle i.e., approximately 3.14 in decimal.
Significance of Pi123
Pi has a broad range of importance covering all aspects from daily activities from cooking to big projects like construction of buildings. Since it is vital part of mathematical calculations that is applicable in various dimensions.
How to Practically find Pi123 in simple Steps.
The process of finding is very interesting.
Step1. Draw a circle of any diameter.
Step2. Take a string and place it on the circle such that it covers the circle completely.
In above image you can see the circumference covering whole boundary of the circle.
Step3. In next step you have to straighten the circumference string and measure the length of circumference with the ruler.
Step4. Now measure the diameter of the circle.
Step5. Now use the formula for the Pi which is as follows
Pi(π)= Circumference / Diameter. 
So, you will get the value of pi123 which is 3.14 regardless of the size of the circle. Value is pi remains constant whatever the size of the circle its radius and circumference.
Uses of pi123
Talking about the uses of pi it is being used in various fields of life. No matter it is Mathematics, science, chemistry, physics, computer science or engineering π is playing a vital role to ease our long calculations.it is also used in research process on a bog scale to get results efficiently and flawlessly.


 Trigonometry and Geometry

Pi tells the functions of Sine and Cosine which solves various mathematical complications. Pi is widely used in geometrical calculations. It is key element required for the measurement of circles. Primarily it tells circumference and area of the circle.


 Pi123 in Mathematical Theories and Series

Pi is used in Leibniz formula and in infinite series expansions which shows significance of pi. Along with this pi has important part in many areas of number theory like continued fractions.


 Pi123 for Computer Programming.

Pi plays its role for designing computer graphics. It is also essential for computer programming. Robotic movements, signal frequencies, and animations are completed with usage of pi.
Pi123 the formula family
Pi provides us a big family of formulas to solve our realworld problems quickly and efficiently. Such as


 Area of Circle

(πr2)


 Circumference of Circle

(2πr)


 Surface Area of Circle

(4πr2)


 Volume of a Sphere

4/3 (πr3)
finding areas of circles(πr2), finding circumference of circle(2πr), finding periods of trigonometry functions and finding sum of the infinite series and finding volumes of sphere and cylinders are few examples of uses of pie.it appears much more times in geometry, trigonometry and calculus as well.
