pie, pi, π

 Pie or pie means a fruit, cream, meat or vegetable filling baked in a pastry crust--
We still have some pumpkin pie. Do you want some?
I was thinking of making a beef pot pie for dinner.

Pi or pi ( rhymes with pie ) is the  Greek letter π, used to denote the relationship between the radius of a circle and its circumference or area--
The circumference of a circle is equal to 2πr.
Many mathematicians have been fascinated by π, as a fraction that never repeats or ends. People once called it "squaring the circle".

Now that you know that, you can say--
"Maybe we should take a break from calculating pi, and have a slice of pie."
