Pi is irrational and goes infinitely, so there are always new digits to be calculated.
No scientist is trying to find the value of PI. They know it. Pi is 4 times the arc-tangent of 1 OR Pi = 4 x atan(1). The exact digits go forever but that doesn't mean they change. The digits of the value of pi will always be the same, it just can't be written completely or exactly in normal decimal number notation.
For mere mortals, like you and me, it's just as good to say 'three and a little bit'!
The average value of pi is a very small number, 3.14 to be precise, but that value od pi is when it is not extracted and stretched millions of times. Scientists are puzzled as to what the value of pi actually is, but 3.14 is more than enough for children in schools.
Lots of scientists have worked on evaluating pi. The question needs to be a little ,ore specific.
The value of Pi is 3.14 so the value of Pi by 2 is 6.28.
None because the exact value of pi has never been finally figured out and that all we know is that when the circumference of a circle is divided by its diameter that it is the value of pi which has been worked out to billions and billions of decimal places and still its exact value remains undiscovered.
There have been many estimations of Pi by many scientists over the years. To answser this questions, more information is needed. You might also see the link on the history of Pi.
There can be no "closest" value. The area is pi*r^2 Using pi = 3.14 gives the area as 28.26 sq inch Using pi = 3.14159265358979 (Excel default), gives the area as 28.2743338823081 sq inches which will be closer to the true area. The value of pi has been calculated to over 10 trillion digits and each additional digit in the value of pi gives a value for the area which is closer to the true value. . And, the value of pi can be calculated to still greater accuracy which would give a closer 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.
It is pi*d where d is the diameter of the circle. Since pi is a transcendental number, it is not possible to express its value exactly and so any value used for pi (3.14, 3.14159 or pi to 10 trillion digits) will still lead to an approximate answer.
