Why is the number pi important enough to have its own symbol?

Question

I never understood what was so special about the number...explain.

Answer 1

Pi is a fundamental constant of circles and waveforms. It is used so often that it needs its own symbol. Also there is no way of writing it accurately using numbers so to avoid errors the symbol pi is used.

Other interesting constants have their own symbols:
e=natural exponent
C=speed of light

Answer 2

pi is very special. it is a random non repeating decimal that solves the relationship of a circle to its diameter for area and circumference. Most of Trigonometry and geometry is dependent on this number. 22/7 and 3.14 are only approximates. The relationship is much more complex. Math would hit a brick wall without the understanding of pi.

Answer 3

Because after a great meal, there is nothing like a bit of pi to finish it off.
Think about it, you're getting lethargic because you just ate a bunch of turkey, beef, or veggies and you have a bit of a nagging hunger pang... What could round out this excellent, yet not quite totally filling meal?
Good old 3.14... it fills you up, but won't slow you down!

Answer 4

It is the "conversion factor" for, among other things, changing a diameter to a circumference. In effect, you are taking a linear dimension and making it curved.

Without pi, it would be a very angular world.

Answer 5

π has puzzled mathematicians since Archimedes.It is beauty and it is like a ghost fog. Constantly looping numbers in quadraic fashions that num and excite the mind of the observer.

Answer 6

Because it is the basis for the circumference of the circle
