Consider a distribution with an unknown parameter pi. If the true value of pi is not known but has been estimated, then the estimated value is usually denoted by pi-hat. This is to distinguish between a known parameter and an estimated one.
The surface area of a cylinder can be found using the following formula - SA = 2(Pi*r2) + (2*Pi*r)*(H) Pi = Approximately 3.14 r = Radius of the base of the cylinder H = Height of the cylinder
2 pi r h
2 x pi x r

There is no formula for Pi, it cannot be represented by any formula. It is a fundamental constant.
The value of pi is the circumference of a circle divided by its diameter
Evopi = evw/pi – evw/o pi
Pi is the value of a circle's circumference divided by its diameter and its true value has never been discovered because it is an irrational number
Srinivasa Ramanujan
A formula is used to find the numeric value of an answer. For example: pi*radius2 = area of a circle in square units
The circumference is found by doubling the radius, and multiplying that number by the value of PI. The formula is Pi x 2rThe area is found by squaring the radius, then multiplying that number by the value of Pi. The formula is Pi x r2 The letter r in both cases represents the radius.
I don't think it was the same person. And there are several formulae to determine pi; which one do you mean?
archimedes, pi is the name of the greek letter p, which was used as the shortened version of the greek word perimeter,or circumference of a circle. archimedes was looking for a formula to find the area of a circle, and he required a more accurate value for the constant pi. previously pi had been assigned a very approximate value of 1/3 or 22/7.
actually pi existed thousands of years ago the first reference comes from the vedas which tells pi divided by ten accurately to 15 decimals. in 2500 to 3000 bc.then babylonians,egyptians,greeks,indians,e.t.c have approximately found the value of pi.archimedes told that pi lies between 3.1429 and 3.1408.aryabhata describes pi as 3.1416.indian mathematical genius ramanujam has invented a formula for pi,using this pi's value can be found correctly to billion decimals.recently in 2010 a super computer using his formula calculated pi to 10.6 trillion decimals.
