It's Pi Day and is celebrated at 1:59 PM today. Pi (π) Day was founded at MIT and is a celebration of the mathematical term Pi. It is approximately equal to 3.14159 and is used to calculate the area and circumference of a circle. The formulas are Area = Pi x radius squared
(A=πrsquared) and the circumference = 2 x Pi x radius or Pi x diameter (C=2πr = πd).
I bought my grandchildren a Boston Cream Pie last year and this year my oldest grandson asked for a Cherry Pie to celebrate the day. I will probably stop and see them on the way home.
Its just a fun way to celebrate the day. It is a geeky thing but being an engineer I guess I'm a little geeky. My daughter said last year that no one not in school knows what Pi is and I told her I use the term weekly.
I did buy a cherry pie to share with the grand kids. The youngest wanted a bite immediately.
So the formulae Pi R Squared is wrong, as you can plainly see Pie R round. LOL
