I've been told that Pi was 3, not 3, 1416...Now what's the truth?

Answer 1

Hi, well despite all of the above I believe that Pi is a sign/letter in classical greek language. By convention and also lack of imagination mathematicians and other dudes decide to asign it the value 3, 1416..... which is an error. Greeks did not have numbers as romans or egyptians did. Greeks used their letters as numbers much in the way the hebrews did and do. So e.g. A alpha could be 1 or alpha with a mark 100 etc etc. Yet never, and I repeat never the letter Pi as any other greek letter had whole numbers, not fractiones, incompletes, irrationals, Fibonacci etc etc. Yet, as when Pitagoras was trying to figure out a formula that could always apply equally to find out the length of a circunference in the most accurate way, Pitagoras, who was a crazy mother, and believed in numbers and Maths as something sacred, muvch in the same line that anyone else believes in the Holly Ghost, Buda Manitu or nothing, he chose conventionally, that ease after trials in reuniomnj with his peers that the value of Pi was, 3, 1416.... Yet since it is a formula, and the objective is to find a way to get the most aproximative number, and since Pi has never been completed, he should have chose to maintain Pi as 3 and variate other of the elements of the formula. Like that he would have found that you could also get a number, maybe even more accurate, or at least not infinite, by establishing that Pi is 3 and the formula could go something like R or O = 1,9100.... x pi x radius of the circle. Wher Pi would be 3 and instead of the formula being
R or O = 2 x Pi x r
it would be
R or O = 1,9100.... x Pi x r

The good thing of maths is that as you can move the numers around an equation or any equality the you can always obtain the numers you need by changing the value of some other and hence why Pi has been said to be related to the measurement of the piramidds heigh, distance to the sun, and much mubojambo. So at least initially Pi was a letter, or linguistic sign today is represente by the letter P, and that has a phonetic sign that sounds Pi, but that in greek times it had a value within the greek alphabet of 80, Pitagorians, as usual disented and made it equivalent to óricos 100, and if it (P), had an horizontal line above it would represent 100.000. So truly Pi is not 3, 1416..or whatever, Pi is a sign that is conventional, reached by agreement of linguists and also mathematicians which did not agree between them.

In any case one could say that Pi represents 3, 1416...or as some intolerants will point out it represent really 3, 1415....But in itself Pi is not anything. And they couuld have figured out a better and more precise way to find out the lentgh of the circle. As I showed above...just they where so in love with the misteries of Pi and Pitagoras, that they rather be inaccurate and invent a formula that didn´t reallycut the cheese...

Mathematics, mathematician say is the universal language...this is another bull***** since before years ago every lculture had their own numers often letters, other pictures, others like latins using the shape of the fingers and positions of the hand etc....so if you went to other country doing business was difficult since you needed a translator of language and also a translator of maths, yet usually Mathematicians are so ignorant about so many things that are not pure math. even the history of numbers, systems and rest that they really believe that Pi is whatever..

Best regards to all of the above, and hopefully someone will understand what I mean and maybe come out with an alternative formula to find the length of the circunference wich was called Ar and Ra depending if it refered to disks like the sun or discs in the ground or conceptual etc

Answer 2

Here is a very easy way to see that Pi is bigger than 3.
The definition of Pi is set up so that if you have a circle with radius 1, its circumference is 2*Pi. I'm going to show this must be bigger than 6, so that Pi must be bigger than 3.
I will use the fact that if you have two points on a circle, the straight line connecting them has shorter length than the arc connecting them.

You need to have a picture in mind of a (regular) hexagon inscribed in a circle of radius 1. See my source for a picture. The six points of the hexagon divide the circle into 6 arcs, and the hexagon into six lines. By what I said in the paragraph above, the six lines are shorter than the six arcs. But because the hexagon is made up of equilateral triangles, the lines all have length one. Therefore the six lines add up to 6, and the six arcs, which make up the circumference of the circle, must be bigger than 6. Therefore 2*Pi is bigger than 6, so Pi is bigger than 3.

Answer 3

No way pi is 3!
Pi is an infinite decimal, i.e pi has infinitely many numbers to the right of the decimal point.
For the sake of usefulness people often need to approximate pi. For many purposes you can use 3.14159, which is really pretty good.

Answer 4

as many have said pi is an infinite decimal 3.1415926535...
pi is most certainly NOT 3.

i also want to clear up something pi is NOT equal to 22/7. 22/7 was an early approximation by the greeks or mayans, while it is kind of close to pi they are not equal

Answer 5

Pi is the rationo of the circumference of a circle to its diameter

Pi = circumerence / diameter

π = symbol

π = 3.131592654 . . . . .is a num repeating number non terminating number go on to infinity

π = is a irrational number

3.141592653589793238462643383279502884197169399375105820974944592.com

Answer 6

Whoever told you Pi is 3 needs to go back to school, or is lying through its teeth.
Pi is 3.141592653589... and it goes down with more decimals like that to infinity.

Answer 7

π = 3.14159 26535 89793 23846 26433 83279 50288 41971 69399 37510 58209 74 944 59230 78164 06286 20899 86280 34825 34211 70679 82148 08651 32823...

it is impossible that pi is equal to 3, but approximately equal to 3, pi also equal to 22/ 7

Answer 8

Pi was 3.1416 if they told you it was 3 they almost round it up

Answer 9

Pi goes on forever, it is estimated 3.1416 but we have not found all the digits and may never find them.

Answer 10

Pi is 3.14. The actual number has more decimal places, but if you need the whole number, it is 22/7.
