What is Pi?And what is the square root?

Question

I know that pi is 3.something

P.s. i wanna know what it is SO FAR!!! not to be told noone knows yet!

Answer 1

all i no is 3.14159265

square root is 1.77245385

Answer 2

pi=(22/7)=3.14

sqrt(22/7)=1.77281052085

Answer 3

pi is an estimated value we used to calculate things like area of circle and etc!! ^^

mmm...square root is ............... i don't know how to explain, sorry!! :D

Answer 4

Generally, it is known as 3.14, or 22/7 (22 over 7)

On a calculator, 3.141592654 are all that fits, sometimes without the 4 on the end.

941511609...

as you can see it keeps going...I've divided it so that there are approxiamately 10 decimal places to each line, and approxiamately 10 lines per section...besides the last one of course...

that makes it around 409 decimal places in what i just gave you...but there are definately more...

The square root of pi as far as I know is 1.77245385

hope it helps

Answer 5

"Pi" is defined as the ratio of a circle's circumference to its diameter.  In other words, if you take any circle, measure it's circumference (the distance around the rim) and divide that by the circle's diameter, you always get the same number, pi.  It is approximately equal to 3.14159.  

I say "approximately" because in reality, there's no way to write it out in full.  The decimals go on forever without any pattern.  This is because pi is what's known in mathematics as an "irrational number".

People who have said that pi is 22/7 are WRONG.  22/7 is only an approximation, and a pretty bad one at that.

There wasn't a single person or group who "discovered" pi.  A number of different cultures came up with the idea and their own approximation, all independently of each other.  It's a very useful number because it turns up in a lot of other things.  For example, the area of the circle is always pi * r^2, where r is the circle's radius.

>>P.s. i wanna know what it is SO FAR!!! not to be told

>>noone knows yet!

To say "no one knows yet" is untrue.  We KNOW what the exact value of Pi is.  These days it's just a question of how many decimal places you want to take it to.  We know that it goes on forever; we've been able to prove that through other means.  If you're asking what the current record is for calculating the number of decimals places of pi, in 2002 it was up to over 1 trillion.  Though somebody may very well have broken the record since then.

If you're looking for a page that gives pi to a ton of decimal places, here's 4 million:

And if you mean the "square root" in general:

The square root is the number which when multiplied by itself ("squared") gives you back the desired number.  For example, √25 = 5 (read as "the square root of twenty five equals five"). And √36 = 6, √49 = 7, √1 = 1, √100 = 10, etc.  In fact, speaking of irrational numbers: there are a lot of square roots that are irrational numbers, like √2 and √5.

Answer 6

Pi or π is a mathematical constant which represents the ratio of any circle's circumference to its diameter in Euclidean geometry, which is the same as the ratio of a circle's area to the square of its radius. It is approximately equal to 3.14159.

square root--a square root of a number x is a number r such that r2 = x, or in words, a number r whose square (the result of multiplying the number by itself) is x.

Answer 7

In Euclidean plane geometry, pi is defined as the ratio of a circle's circumference to its diameter:

In mathematics, a square root of a number x is a number r such that r2 = x, or in words, a number r whose square (the result of multiplying the number by itself) is x.

a rough fractional eqivalent is 22/7 or 353/113  

Answer 9

"So far"?  PI is a never ending non-repeating string of digits after the decimal (because it is an irrational number).  Just use a calculator to get a large number of digits.
