1. p is the symbol used for this special number Pi is its name (Say it as `pie')
p comes from working with circles.
p is the ratio of the circumference of a circle to its diameter.
This means that you can work out p by dividing distance around a
circle by the length of its diameter.
3. p = 3.14159 26535 89793 23846 26433 83279 50288 41972 ...
The strange thing is that the answer you get can only ever be approximate -
that is, you can never have an exact value for pi. This has fascinated
mathematicians for a very long time and they have kept trying to find ways to
calculate values for pi that are more accurate.

By chosen words the young instruct.
Cunningly devised endeavour,
Con it and remember ever.
Widths in circle here you see,
Sketched out in strange obscurity.''
