What do they mean in math when they say pie?

Answer 1

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, in mathematical terms, means the number 3.14159. Pi is a never-ending number ( it goes on forever after 3.14159)
