Look at this beautiful cone. Even the numbers are beautiful! The volume of a cylinder is the area of the base times the height, right? And for a cone or a pyramid, the area of the base times the hight divided by exactly 3! Isn’t that fantastic? And odd, concidering that something as simple as a diamater has to be multilied by a horrid number like 3.1415926535897932384626433832…. to get the circomference. It doesn’t get any better if you sing it: http://pi.ytmnd.com/ Maths simply isn’t fair, is it? 🙁 And what is more surpricing? The exact 3, or the horrid ∏ ?
