What is Pi Day?
We all know what Pi is. It is a mathematical constant represented by the lower-case Greek letter π. It is the ratio of a circle's circumference and diameter. It can help us measure angles and understand many different things about circles. The value of Pi is 3.14592654 as per the calculator, and you can also write this as a fraction 22/7, even though it is an irrational number.
While we are aware of Pi and its uses, many of us don't know about the 'Pi Day.' It does sound like a festival name, and it indeed is. Taking place every year on March 14th, this day is all about celebrating this mathematical constant 'Pi.' It is celebrated on this specific day because 3, 1, and 4 are the first three significant numbers in this constant.
A series of word problems related to pizza. Example: Ellen makes two pizzas. One is on a pizza tray that is 12" in
diameter. The other is on a pizza tray that is 8" in diameter.
What is the total area of Ellen’s two pizzas?

A series of problems you must work your way through
This is a live circular problem for you to tackle.
You guessed it! A whole bunch of problems that literally revolve around this sweet treat.
Complete the following equations where C is the circumference
of a circle, A is the area of a circle, V is the volume of a cylinder, R is
the radius of a circle, and D is the diameter of a circle.
Example: Find the surface area of one
piece of pie if the surface area of
the whole pie is 63.585 square
inches and the diameter of the
whole pie is 9 inches. Assume the
pie has been cut into 6 pieces.
A reading comprehension for you.
The number pi never
ends, and it never
repeats. It is known as an
because not only does it
go on forever, it is also a
sequence of numbers,
meaning that there is no
pattern to it.
Provide the class with an assortment of circular objects of
different sizes. You could use circles cut out of paper, plates, pie plates, pizza
trays, or even cookies! Have each student choose one or two objects.
Measure the diameter of each circle. Find its radius, circumference, and area.
