Pi was discovered, not invented. It was found, centuries ago, that no matter what size a circle was, the circumference always bore the same relationship to the diameter. They knew, even though they lacked precise measuring tools, that this number was not one which could be expressed as the exact ration of any two numbers. It has been 'refined' down the ages - drawing ever closer to the true figure, but never getting there. As a result, pi is used as a 'shorthand' for a very imprecise figure.
No
They didn't
No. Pi has been around for much longer. There's even a reference to it in the Bible.
the Greeks loved learning He didn't invent pi, pi has been around since Babylonian times mathematicians, like Archimedes, have simply tried to figure out when it ends. He didn't though. It was only until the computer age we figured out it can go out forever.It's been calculated to the 206 millionth decimal place!
[pi^(1/3)]^2 * pi = pi^(2/3) * pi = pi^(5/3) The answer is the cubic root of pi to the fifth power.
No
No. pi was known long before.

'pi' was known before Pythagoras. The Sumerian Civilisation found the constant of proportion between a circles diameter and circumference to be 3.141592..... Later, the Classical Greeks (Pythagoras) gave this 'constant of Proportion' the name 'pi' . 'pi' in the classical Greek alphabet is the lower/small case letter 'p', for Proportion. There it has stayed ever since. Algebrqaically Circumference is directly proportional to diameter. C directly proportional d Equating C = kd 'k' is constant of proportion and as mentioned above given the symbol 'pi' Hence C = pi*d pi = C/d or pi = C / 2r NB ; d = 2r Hence the modern equ'n C = 2pir
Euler is one of the most famous mathematicians of all time and he contributed a huge amount to maths. He is most famous for Euler's equation which unites 5 of the fundamental numbers in maths: e, i, pi, 1 and 0. It looks like this: e^(i*pi)+1=0
(pi)(1/pi)=1.4396 ...
the same as pi squared, which is 9.86960440109
what did Obama invent
His name is ArchimedesHe didn't invent this but he discovered leversHe boasted once that if he had a place to stand and a long enough lever, he could lift the world. He also calculated pi.
