The number represented by pi (π) is used in calculations whenever something round (or nearly so) is involved, such as for circles, spheres, cylinders, cones and ellipses. Its value is necessary to ...

Pi Approximation Day falls on July 22 (written as 22/7 in the day/month date format). It commemorates the common approximation of the mathematical constant π as 22⁄7, which dates back to Archimedes ...

For some, today (July 22) is Pi Approximation Day, but for some others, it is March 14. Pi is the ratio of the circumference of any circle to the diameter of that circle. Greek letter π was first used ...

Pi (π) was known and used ancient times approximated for almost 4000 years. The ancient Babylonians also calculated the area of the circle by taking three times the square of its radius which gave the ...

Today is March 14th, or Pi Day because 3.14 is March 14th rendered in month.day date format. A very slightly better way to celebrate the ratio of a circle’s circumference to its diameter is July 22nd, ...

Archimedes determined the upper and lower range of pi by finding the perimeters of inscribed and circumscribed polygons. By doubling the number of sides of the hexagon to a 12-sided polygon, then a 24 ...
