How do you celebrate National Pi Day?
Pi Day is observed on March 14 (3/14 in the month/day format) since 3, 1, and 4 are the first three significant digits of π. It was founded in 1988 by Larry Shaw, an employee of the Exploratorium. Celebrations often involve eating pie or holding pi recitation competitions.
How did mathematicians discover pi?
The Egyptians calculated the area of a circle by a formula that gave the approximate value of 3.1605 for π. The first calculation of π was done by Archimedes of Syracuse (287–212 BC), one of the greatest mathematicians of the ancient world. In this way, Archimedes showed that π is between 3 1/7 and 3 10/71.
What mathematicians birthday is on Pi Day?
Albert Einstein’s
But Pi Day commemorates pi’s use as a noun. Nobel Prize-winner, physicist and mathematician Albert Einstein’s birthday also happens to be March 14. He would be 141 years old this year. Einstein is best known for developing the theory of relativity and the equation E=MC2.
What is Pi Day and why do we celebrate it?
March 14 marks Pi Day, an annual celebration of the mathematical sign pi. Founded in 1988 by physicist Larry Shaw, March 14 was selected because the numerical date (3.14) represents the first three digits of pi, and it also happens to be Albert Einstein’s birthday—the perfect pi-incidence.
Does Pi end in math?
Value of pi Pi is an irrational number, which means that it is a real number that cannot be expressed by a simple fraction. That’s because pi is what mathematicians call an “infinite decimal” — after the decimal point, the digits go on forever and ever.

How do you use pi in math?
In basic mathematics, pi is used to find the area and circumference of a circle. Pi is used to find area by multiplying the radius squared times pi. So, in trying to find the area of a circle with a radius of 3 centimeters, π32 = 28.27 cm.
