pi is a division of math and since math never changes it is the same value as here in the U.S. and yes i agree with "losers" plz dont make fun of my country

Pi came about, because of an observation that the ratio of a circle's circumference (the distance around it) to its diameter (the length across) is always the same, regardless of the size of the circle. That value is pi.

Assuming this means a circle...\n\ndefn/:\n\nc=circurmfernce\nA=area\nr=radius\nd=diameter\npi=pi (~3.1415926...)\nd=2*r\n\nC=2*pi*r=d*pi\nA=pi*(r^2)...(area is pi*r squared...pie are squared-no there not their round).\nA=pi*(d^2)/4.\n\njust plug and chug...\n\nC=10*pi.\nA=25*pi.\n\nanswer:\n\nit's that simple

PI= π = 22/7 = 3.1428571428571428571428571428571\n\nIn Euclidean plane geometry, π may be defined either as the ratio of a circle's circumference to its diameter, or as the ratio of a circle's area to the area of a square whose side is the radius. Advanced textbooks define π analytically using trigonometric functions, for example as the smallest positive x for which sin(x) = 0, or as twice the smallest positive x for which cos(x) = 0.\n\nAll these definitions are equivalent, they amount to the following numerical value of π, truncated to 50 decimal places:\n\n3.14159 26535 89793 23846 26433 83279 50288 41971 69399 37510

Pi is approximately 3.14159.  It is the never ending number that results from dividing the circumference of a circle by it's diameter.

The Greek letter pi is a constant approximately equal to 3.1415. It is irrational, meaning that it has been proven that it's digits continue forever without repeating, and that it cannot be written as a fraction.\n\nThe definition of pi is the ratio of a circle's diameter to it's circumference, but it has the curious property of popping up all over the place in other forms of math too.

Hi:\n\nRead the question by dreamchost1205 about the number pi and read iroc70 's answer it should explain thing very well.\n\nGood luck and best wishes to you

I don't know this equation, but pi is the greek letter P. it can be used for any variable, but since it is widely accepted as the constant 3.1415 (= a circles circumference divided by its diameter) this would be a dumb decision.\n\nFor example when you need to sum many values, you use the Sigma, but for multiplying many values you use the big PI.\n\ngrtz,\nGB

pi doesn't equal 22/7 or 3.14.  those are just approximates, but fairly close approximates.\n\npi is how many radians there are in a half a circle-approximately 22/7 or 3.1415 radians.  a radian is the degree where the radius of the circle equals the outside segment of the circle at that degree.  (about 59 or so degrees if i remember correctly)

Math: Pi is equals to 3.14141414141414..... actually, it's an infinite number.\n\nEnglish: contraction - (1)A word, as won't from will not, or phrase, as o'clock from of the clock, formed by omitting or combining some of the sounds of a longer phrase. \n                       (2)The formation of such a word. \n\nSOSE: tallest mountain in Australia is Mount Kosciusko\n\nScience: H2O is a molecule of water. it is made up of 2 Hydrogen ATOMS and 1 Oxygen ATOM.\n\n\nI hope I answered all of them correctly!

Radians are based on pi.  A radian is equivalent to 1/(2pi).  Because it is just a ratio of another constant, it isn't based on a physical standard unlike feet, meters, etc.\n\nIt's just like degrees.  A degree is 1/360th of a complete circle, but nobody needs to define 360 with a physical object.  We all know what 360 is.  Similarly we know what 2pi is (it's the circumference of a unit circle).

pi is a perimeter around a circle, it's 3.14 because if we wrote the actual number of pi it wouldn't stop

I do believe it is Pi....\n\n(NOTE: The below information was gleaned from an article in The New Yorker magazine, March 2, 1992, called "Profiles: The Mountains of Pi")\n\nPhysicists have noted the ubiquity of pi in nature. Pi is obvious in the disks of the moon and the sun. The double helix of DNA revolves around pi. Pi hides in the rainbow, and sits in the pupil of the eye, and when a raindrop falls into water pi emerges in the spreading rings. Pi can be found in waves and ripples and spectra of all kinds, and therefore pi occurs in colors and music. Pi has lately turned up in superstrings.\n\nPi occurs naturally in tables of death, in what is known as a Gaussian distribution of deaths in a population; that is, when a person dies, the event "feels" pi. It is one of the great mysteries why nature seems to know mathematics.

when you multiply 247474747474.5 with Pi, you will get 777777777777.... :)

It means 10 times pi.  If you don't know what pi means, its that wacked up #, you know 3.141..............
