People generally celebrate March 14 as Pi Day, because March 14 is also written as 3/14, which represents the first three numbers 3.14 in the approximation of pi. 20 digits for a radius equal to the distance from the earth to Polaris.

15 digits for a radius equal to the distance from the earth to the sun.10 digits for a radius equal to that of the earth.

This basically means that the digits of pi that are to the right of the decimal go foreverwithout repeating in a pattern, and that it is impossible to write the exact value of pi as a number. Pi is also an irrational number, meaning it cannot be written as a fraction (), where a and b are integers (whole numbers).

4 digits are needed for a radius of 30В meters Pi is often written as, or the Greek letter as a shortcut.

To calculate the circumference of a circle with an error of 1В mm: Pi is also an irrational number, meaning it cannot be written as a fraction ( a b, where r is the variable for the radius of any circle and A is the variable for the area of that circle. In this lesson plan for Pi Day or any day, students will use data on the circumference and diameter of various objects to calculate pi. Pi is often written as ПЂ, or the Greek letter ПЂ as a shortcut. A diagram showing how ПЂ can be found by using a circle with a diameter of one.

Calculate pi to the 7th
