If you mean pi as in 3.14159... I can answer. Pi is a relationship that compares the circumference of a circle to the diameter of that same circle by division. In any circle, if you divide the length of the circumference of that circle by the length of its diameter you will get 3.14159... or pi. This can be very helpful to know because it is much easier to measure the diameter of a circle than to measure the distance around the circle (circumference). If you multiply the diameter by 3.14159... you will find the circumference. If C = circumference; D = diameter; pi = 3.14159 theses are some useful formulas: C = D X 3.14159 or D = C / 3.14159 or 3.14159 = C / D

What does pie in math equal?
'pie' does not equal anything in mathematics. 'Pie' can be eaten as an apple pie or a meat pie. If you mean 'pi' , note the spelling. then it approximates to. pi =~=3.14 pi =~=3.1416 pi =~=3.141592 pi = 3.141592.... It is an irrational number, which casually means that the decimals go infinity, and the decimal digits are NOT in any regular order. To date 'pi' has been calculated , by super dupa computers, to at least 50,000,000,000 ( 50 billion) places and still going. NB 'pi' is the small/lower case Classical Greek letter 'p' , and refers to proportion as in C = pi d ( Of circles). 'pi' is the constant of **p**roportion.
In math why does pi represent 3.14?
Pi does not represent 3.14. Pi represents the ratio of the circumference of a circle to its diameter. Pi is an irrational number. 3.14 is but the crudest approximation of pi. A better approximation is 3.1416. Still better is 3.14159. The closest approximation commonly used in real-world applilcations is 3.14159262. If anything, 3.14 represents pi, and represents it very imprecisely. As for why the term "pi" was chosen to represent this important concept in mathematics, it was chosen because it is the initial letter of the greek word for "perimeter".
What does a backwards 3 mean in mathematics?
Do you mean this symbol ∈ (or backwards 3) if so, it means is an element of; Also, ∉ (with strikethrough) (or backwards 3 with strikethrough) is the symbol for "is not an element of" used in set membership. See also Element (mathematics) and Set (mathematics)
What is the deffinition of pi?
I assume that you mean "the 'definition' of pi", which is the circumference of a circle divided by it's diameter (c/d).
What is 3 pi?
If you are meaning it in sense of a geometry, the it's 3 * 180 degrees (which is what they mean by pi) = 540 degrees.
