Happy A/r^2 Day

Today is March 14th.  Or, abbreviated today is 3.14; the value of Pi.

Happy Pi day!

If you divide the perimeter of The Great Pyramid by it’s height, you get 2π.

By extending π to only 9 digits you can calculate the circumference of the earth to within 1/4 inch.

A river’s meandering is described by its sinuosity – the length along its winding path divided by the distance from source to ocean as the crow flies. It turns out the average river has a sinuosity of about 3.14.

Finally, what do you get if you divide the circumference of a jack-o-lantern by it’s diameter?  Pumpkin pi.

Enjoy
