What is correct value of pi, ?
Answers:
pi= the circumference of a circle divided by the diameter
approx 3.14159
3.1415...never ending
22/7
the corect answer is 22 devided by 7, and its on going
3.142857
22/7
and if you want the exact value in decimal, it takes
a whole book to write it
I'm not EXACTLY sure what your question is, but pie equals 3.14
I hope you're talking about math.
How many decimals do you want?
I'm sure that you have the answer by now.
Try this link for an explanation of pi.
Hi i always thought is was 27? not to sure now though.
maybe the link will help explain it better.. good luck
no computer can give the exact value of Pi with all its decimals but how's this for a start
3,141 592 653 589 793 238 462 643 383 279 502 884 197 169 399 375 105 820 974 944 592 307 816 406 286 208 998 628 034 825 342 117 067 ...........
22/7 is only an approximate value.
infact 7pi/22 - 1 can be proved not to be 0
. its never ending...
3.1415926535897922 -- there's a detailed article on how pi is calculated at the URL given below.
To 50 places it is:
3.14159 26535 89793 23846 26433 83279 50288 41971 69399 37510
ALL WRONG..CHERRY PIE...£2.99 IN TESCO
pi is based on 22 divided by 7
it is infinite
for all practical purposes, 3.14 is acceptable
The 'correct' value can't be written down because it's full expression goes on forever.
22/7 is a good approximation
355/113 is an even better approximation
3.14159 is the best decimal expression to 6 significant digits.
If you write Pi to 50 decimal places the value is so accurate that the error in circumference of any circle which will fit within the size of the known universe is less than the diameter of a proton.
It has been evaluated to over one trillion decimal places.
3.1428571428571428571428571428. since it doesnt end it just loops back to the came values which will be 142857
yesterday coincidentally I read that the Japanese once calculated the valued of pi to 1.24 trillion decimal places. The people answering 22/7 are not giving you the value of pi but the closest fractional approximation. A typical calculator will give 3.14159265 but of course the value ( decimal places ) continues indefinitely. For a question on a test or assignment the calculator value is sufficient to get the answer.Philosophically pi has no determined conclusion and apparently no pattern of repetition.

When you say "correct", it depends on what your use of pi will be. If you are trying to determine the circumference of a tire based on the diameter, they 3.1416 is close enough. If you are trying to determine the diameter of a tree by measuring around it, 3.14 is "correct". If you just want to know the diameter of your camel's belly is by measuring around it, 3.1 will do it. I see your question as passive terrorism. You really are just trying to see how much American time you can waste by asking such a question. Well, that's enough of my time.
If you go to your computer's scientific calculator and select pi it will give it to about 30 places.
I teach this to three year old children in a simple way. The answers, of course, are correct above. But, just for fun:
1. Make a big circle on a page of paper.
2. Mark the centerpoint. Fold the circle in half and then refold another way in half. Open up and you'll see your centerpoint.
3. Use string or cord, about as long as your leg
4. With the string, measure across from one side of the circle to the other side right through the centerpoint. That's the diameter length.
5. Cut the cord so that you have three strings that are as long as the diameter.
6. Now, place those three strings around the outside edge of the circle. The outside edge is called the circumference.
7. It takes all three strings to go around the circumference. But, not quite. There's a little piece missing.
8. The circumference of a circle is always like that. It takes three strings as long as the diameter, plus a little piece, to go all the way around.
9. "Pi" is the Greek letter we use for that number, three and a little piece.
10. The number for Pi is 3.14159265
11. Pi means, it takes three diameters, plus a little piece to equal the circumference.
12. Pi is a mysterious number because it never ends. The actual measurement of that little piece goes on forever, as far as we know so far.
13. Here is a website about the number Pi . Computers are taking Pi to about 2 billion places I believe.

22/7
Or something :P
3.14285714.........
actually pi has no real value.it is an imaginary no.
the correct value of pi? Circumference of a Circle divided by its Diameter. That's the most correct answer, if someone gives you 22/7, that is an approximate answer, if other gives 3.1415.10^100000000 digits later, that's a rounded answer.
Someone (don't know who), has proven that the value of pi is irrational, you can't describe it as x/y, and thus you can't define it's exact value as a number either. Like square root of 2, or Phi, the Golden Ratio. Pi is usually approximated by the value of 22/7 or 3.14, but they're not the exact value, you can be writing every milimeter of the universe with numbers and still won't find the last digit of pi.
the answer is - under the numerical system that
we have at the moment,there is no correct value
of pi
otherwise,it is the ratio of C to D
where D =the diameter of a circle
and C =the cicumference of a circle
i hope that this helps
if you divide 22 by 7, it will give you the correct value of pi.
The value of pi goes on and on as everyone has said.
If you are using pi in a calculation 3.14 is fine, unless you have the new claculators, you can just use the pi key.
