Pi is composed of exactly how number system?

Can the problem of computing the number pi be solved exactly?

No. Pi is a neverending number.

Can pi be represented by a rational number in a numbering system that is not to base ten?

No. In fact, because pi is a transcendental number it cannot be represented in such a way even in a base composed of "ordinary" irrational numbers like square [or other] roots.

How do you work out if pi is irrational?

You don't: it simply is. Irrational refers to the fact that pi cannot be exactly defined using a decimal system. Pi is not 3.14, it is in fact 3.141592653589793238462643383279502884197169399375105820974944592307816406286208998628034825342117067982148086513282306647093844609550582231725359408128481117450284102701938521105559644622948954930381964428810975665933446128475648233786783165271201909145648566923460348610454326648213393607260249141273724587006606315588174881520920962829254091715364367892590360011330530548820466521384146951941511609... The fact that this number goes on and on means it is irrational

What do you have to divide by to get Pi?

Pi is an "irrational" number, which means that there are no integers that form a ratio exactly equal to pi. In other words, you cannot divide any whole number by any other whole number to get pi. 22/7 isn't too far off, and 355/113 is fairly close, but they're not exactly pi.

How many place values in pi?

Pi cannot be expressed exactly as any fraction (including as a fraction of powers of 10, which is what a decimal fraction is). There are an infinite number of place values in the number 'pi'.

What is pi times pi exactly?

It is exactly pi2. Any other way you express it would be inexact. Pi, or any number that includes pi (like pi x 2, pi + 1, pi2, etc.) are irrational numbers - they can't be expressed as a fraction, with integers in the numerator and the denominator.It is exactly pi2.

What is pi times 42?

Since pi can not be written exactly as a decimal or fraction, you have two options:1) Keep the answer as 42 pi, to have the exact value.2) Round the number pi to the desired precision, for example 3.14, or 3.1416, then carry out the multiplication.Since pi can not be written exactly as a decimal or fraction, you have two options:1) Keep the answer as 42 pi, to have the exact value.2) Round the number pi to the desired precision, for example 3.14, or 3.1416, then carry out the multiplication.Since pi can not be written exactly as a decimal or fraction, you have two options:1) Keep the answer as 42 pi, to have the exact value.2) Round the number pi to the desired precision, for example 3.14, or 3.1416, then carry out the multiplication.Since pi can not be written exactly as a decimal or fraction, you have two options:1) Keep the answer as 42 pi, to have the exact value.2) Round the number pi to the desired precision, for example 3.14, or 3.1416, then carry out the multiplication.

Who made the number pi?

Nobody made the number pi. It existed before mankind, before the sun and the solar system.

How can one determine the number of pi electrons in a molecule?

To determine the number of pi electrons in a molecule, count the total number of electrons in the pi bonds and lone pairs that are part of the pi system. Pi electrons are the electrons involved in pi bonds, which are formed by the overlap of p orbitals. Lone pairs in conjugated systems also contribute to the number of pi electrons.

Does pie equal exactly 3?

No it does not exactly equal 3. Pi (that's how you spell it in math terms) exactly equals 3.14159265*just a note Pi does not in fact equal exactly 3.14159265 it is an irrational number therefor has no exact value although its decimal places will continue infinitely :)

Is pi an irrational or a rational number?

Pi is an irrational number. A rational number is one that can be expressed as a fraction (or ratio), e.g. 1/3. There are fractions that are near Pi, for example: 22/7 = 3.142857 (PI = 3.14159265...) A closer fraction is: 355/113 = 3.14159292 However whatever fraction you have, you will never get exactly PI. Hence it is irrational See the links for proofs that pi is irrational.
