Q:
# Who Came up With Pi?

**William Jones, a mathematics teacher, first came up with pi; however, Leonard Euler is often credited with its introduction into mathematics.** Jones wrote in his second book "Synopsis" that he believed pi was actually an irrational number, and the ratio should be represented by a symbol.

Before pi became widely used, the ratio was called "quantitas in quam cum multiflicetur diameter, proveniet circumferencia" a phrase that is Latin for "the quantity which, when the diameter is multiplied by it, yields the circumference." The fractions 355/113 and 22/7 were often used for pi. However, those ratios are not an accurate representation of the true ratio of pi.
