The value of pi is determined by a circle's circumference divided by its diameter and its exact value has never been discovered because it's an irrational number
For example, by calculating the surface of a circle, using an integral.
Pi is a number (which is 3.14....) which you will always get when you divide a circumference of circle by its diameter...
The value of Pi is 3.14 so the value of Pi by 2 is 6.28.
The area of the base of a cylinder = Pi times Radius squared. Diameter of a cylinder = 2 times Pi times Radius. To find the diameter derive the area of the base by Pi and then square root the answer. That will give you the value of the radius. Multiply that answer by 2 times Pi and you will have your answer.
The value of pi (Ï€) is3.1415926535897932384626433832795028841971693993751.........
The approximate value of pi is 3.14159265.
You get the value of pi by dividing the circumference with the diameter of a circle. pi = c/d
The value for Pi for math is 3.14. Pi is the 16th letter in the Greek alphabet.
No one has fully discovered pi. Pi is believed to be irrational.
Not sure what the 227 is for but the value of pi is 3.14159265
