In Geometry, pi lets us determine a circle's circumference if we know the circle's diameter (or radius, which is half the circle's diameter). We can determine this because the circumference is always pi (~3.14) times larger than the diameter of the circle. So, if the diameter of a circle is 1 foot, we know the circumference is 1 ft x pi which is approximately 3.14 feet. The formula for circumference is C = 2 x pi x r. Multiplying the 2 and the r (radius) in that equation gives you the length of the diameter of the circle, so the equation can be rewritten as C = pi x d which is what I used in the example in the last paragraph. Pi is also used to find the area of a circle by using the equation A=pi x r2. Calculus was used to create that formula which is beyond the scope of this explanation.
The 'symbol' is a letter in the Greek alphabet - which is pronounced 'pi'. The connection between the letter and the ratio of the diameter and the circumference fo a circle may come from the fact that the letter pi is the first letter of the Greek word for perimeter, and the word for periphery.
There are no such theories, at least not by sane people. There is no reason to believe that the digits of pi have anything to do with dates of important events.
All you need to do is multiply the diameter by pi. Pi's decimal equivalent is 3.14159... The reason that I put the triple period was to signify that pi is a non-ruccuring, or transcendental number, which means it has infinite digits after the decimal. For general purposes though all you would need to know is that pi = 3.14 since you would not likely need to calculate anything past two decimals.
[pi^(1/3)]^2 * pi = pi^(2/3) * pi = pi^(5/3) The answer is the cubic root of pi to the fifth power.
(pi + pi + pi) = 3 pi = roughly 9.4248 (rounded) Well, if you use the common shortened version of pi which is 3.14 and add that 3 times, you get 9.42.
Pi, is an irrational number (it cannot be written as a fraction) For this reason, 3 times pi is also irrational.
its a very long reason why pi is 3.14 but that's just the way it is- pi is 3.14 and that's that :)
One reason Pi dislikes his name is because it sounds like the mathematical constant "pi" (Ο), leading to teasing and mockery from classmates. This association causes Pi to feel self-conscious and embarrassed about his name.
An irrational number has no end and pi is infinite and has no end, therefore pi is irrational. Note: There are computers that have been computing the number pi for a long time and there has been no end yet. The numbers just keep going on and on and there is no rhyme reason or pattern to it.
Pi is a constant, a number that for some reason is always created when you do similar problems. For example, If you divide the circumference(length around the circle) of a circle by its diameter(line that divides it in half) you will always get 3.14195926535..., or Pi.
The significance of Pi's name in "Life of Pi" is twofold. Firstly, it is derived from the mathematical constant pi (Ο), symbolizing an infinite, irrational number reflecting Pi's own vast and complex nature. Secondly, the nickname Pi is a shortened version of Piscine, the main character's original name. This dual meaning represents Pi's ability to contain seemingly contradictory elements within himself, such as faith and reason.
They're secret for a reason, get initiated if you really want to know.

(pi)(1/pi)=1.4396 ...

pi r^2 h is used to determine the volume of a cylinder because when determing the area of a shape you first have to determine the area of the the base of the object and then multiply it by the height. The base of a cylinder is a circle and to find the area of a circle you use pi r^2 and hence the reason why pi r^2 is used to find the volume of the cylinder.
the same as pi squared, which is 9.86960440109
