Pi Day is celebrated on March 14th (3/14)
around the world. Pi (Greek letter “π”) is the symbol used in mathematics to represent a constant —
the ratio of the circumference of a circle to its diameter, which is
approximately 3.14159.
The area of a circle. A = πr2
Where ‘r’ is the radius
(distance from the center to the edge of the circle). Also, this formula is the
origin of the joke “Pies aren’t square, they’re round!”
The volume of a cylinder. V = πr2h
‘h’ is the height of the
cylinder.
