Where does the term pi come from and how many digits are actually in pi?

Hi Mary,

As for where pi comes from you can read Chris' response to an earlier question. If you express pi as a decimal number then the number of digits is not finite. In Chris' response above there is a link to The Pi Home Page. You will find a lot of information there on pi.
