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.
William Jones and his Circle
pi is a symbol that we all use and it looks something like this....
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).
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.
3.14159265 etc. Correct spelling is: Pi no 'e'
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).
Nothing!!!!! , Because 'pie' is the pie that you eat, like Apple pie, or Meat pie. If you mean 'pi' , note the spelling, then this refers to the constant of proportion of circles. Circumference = constant of proportion X diameter, Algebraically written as : - C = kd Where 'k' os the constant of proportion, and for circles it is given the name 'pi' For circles however large or small have 'pi' as the constant. 'pi' has the numerical value of 3.141592... Which is an IRRATIONAL numbe. and is approximated to 3.14, 3.1416, 22/7 for school learning purposes. 'pi' is the small case letter 'p' from the Classical Greek Alphabet, and refers to constant of PROPORTION. As a Classical Greek letter, it looks like a set of football goalposts, with a curved leg on one side. Casually , IRRATIONAL means that the decimal digits recur to infinity, AND the decimal digits are NOT in any regular order. What you are given in school ( 3.14 etc.,) is only an approximation. Supa Dupa computere have calculated 'pi' to at least 50 billion places and still going!!!!! Hope that helps!!!!!
Pi=3.14 in basic math
