pi = circumference (C) / diameter (d)
You could use the rational approximation 22/7
To be more precise 355/113
No one because the volume of a sphere is 4/3*pi*radius cubed but it is only an estimation because the exact value of pi has never been found.
circumference and diameter
who invented, or came up with "pi" in math? How did they come up with the estimation of 3.14?
The value of Pi is 3.14 so the value of Pi by 2 is 6.28.
The first known calculation of the value of pi dates back to ancient civilizations, but the earliest recorded estimation is attributed to the ancient Greek mathematician Archimedes around 250 BCE. He used a geometric approach involving inscribed and circumscribed polygons to approximate pi, arriving at the value between 3.1408 and 3.1429. While earlier cultures had approximated pi, Archimedes' method was one of the most systematic and influential in the history of mathematics.
it means estimation about or nearly estimation is my best answer
The approximate value of pi is 3.14159265.
The value of pi (Ï€) is3.1415926535897932384626433832795028841971693993751.........
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.
Area = pi * radius squared A = pi * r2 Best to use the calculator value of pi to 9 places for more accurate answers.
