Steve1. It means the difference between the two worlds that connect cheese and bread.
2. Pi is the Greek letter that stands for the relationship between the diameter of a circle, and the circumference of same. It's about 3.14159 and change.
In other words, the distance AROUND a circle is about three times the distance Across that same circle, to the (edge to edge through the center).
This ratio is CONSTANT, no matter how big the circle.
No one "Invented" Pi - it was "Discovered" because it had always been there.
pi is an irrational number meaning you can take decimals out to infinity and it never ends or repeats: 3.141592653589793238462643383279502884197169399375105820974....
but it is often shortened to 3.14 to find the circumference of a circle.
only digits of pi i know

Pi, denotedπ, is just a mathematical constant.A constant is just a variable, or symbol, that holds (or represents) a number.
It is approximately equal to 3.14, so it comes between 3 and 4 on the number line.
The number Pi represents the ratio of the circumference of a circle to it'sdiameter. The proof for this is long, and beyond the scope of this question. Seeing the ratio visually though, might help.
Circumference (C) = 2πr, where r is the radius of a circle
Diameter of a circle (d) = 2r
Pi is the ratio of circumerference and diameter:
(2πr) / (2r) = π
3.141592653589793238462643383279502884197. Pi is an irrational number, which means it is not equal to the ratio of any two whole numbers.
It's the number you get when you divide the diameter of the circle by its circumference. Easy.
To get the circumference of a circle by only knowing the diameter, multiply the diameter by π, which equals 3.141592653589793238462....

What does the math version pi mean?
The number for pi is: 3.1415926535897932384626433832795
Where did the math symbol pi in math come from?
several equations' answers come out to 3.14 and so on, thats pi
Why is pi important to the study of math?
Pi is important to the study of math because is can be used in many ways. For example, you can use it to find the circumference of a circle and the volume of a sphere. I am not really sure how people calculated that pi works for that, but it plays a big part in our math history.
What is the sq. footage of a 20 ft. circle?
I'm guessing you mean 20 ft. circumference? With a 20' circumference, here's the math. C=20; C(r)=2*[pi]*r; 2*[pi]*r=20; r=10/[pi] A(r)=r2*[pi]; A=(10/[pi])2*[pi]; A= about 31.831 sq. ft.
What does pir2 mean in math terms?
Pi r 2. Pi is a numerical constant roughly 3.142. r is the radius of a circle. 2 in this case is the square of the radius. All this adds up to the area of a circle. Area=Pi x (radius squared)
