Pi was introduced by the ancient Greek mathematicians; history does not record the name of a specific person who is responsible for this idea.

In math terms, pi, means 3.14, which is a everlasting decimal, that is just rounded to make your math easier. So pi, means 3.14 in math terms.

pi is a symbol that we all use and it looks something like this....
who invented, or came up with "pi" in math? How did they come up with the estimation of 3.14?
Yes. in fact, the Ancient Greeks invented pi.
If you are referring to the number that is used to describe the ratio of a circle's circumference to its diameter, then, yes, in terms of math it is spelled pi. Pi equals out to about 3.141529+ and goes on infinite (never ending).
3.1415........... (in more simpler terms, it is a ratio). Pi represents the ration between a circles circumference to its diameter. So in other words, pi=(c/d), making pi a constant [3.1415....]. Isn't math just wonderful!!
It means a rotation of pi radians (180 degrees).
Foucault's last conundrum.Fermi's last theromExact value of Pi.
3.14159265 That Pi? Many people use Pi. I use Pi in my math class.
If i remember the 'ol math class circle area is equal to radius squared times pi so 20x20x3.14 = 1256 meters squared
