How long would it take to recite all the known digits of PI?
Infinitely long since there is an infinite number of digits.
What is the formula to find the circumference of a circle when the diameter is known?
It is NOT a formula but an EQUATION . The answer is C = pi*d This equation has been known for thousands of years. It can also be in the form of C = 2 pi r NB 2r = d Also A = pi r^(2) for the area of a circle.
Why is pi an inrational number?
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.
What is the longest known value of pi?
The longest known value of pi is now into the hundreds of billions of digits.
Pi is known to be over how many digits long?
Pi is infinite. The current number of digits calculated is over ten-trillion. If you want to find a pretty good estimate, divide 22 by 7.
Did William Jones invent pi?
No. pi was known long before.
How long were mathematicians been studying pi?
Pi have been studied for over 10 centuries!!!
Information about the discovery of pi by aryabhatta?
Aryabhatta did not discover pi - it was known long before him. He found a more accurate value and a method for calculating pi to greater accuracy than was previously known.
What is pi hat in statistics?
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.
When was pi known as a value?
Since ancient times it was known that when a circle's circumference is divided by its diameter the quotient is pi which is an irrational number and its exact value has never been finally determined.
Which Swiss Mathmematician invented pi?
pi is a universal constant and was not invented by anybody. It was known to the ancient Babylonians long before the Swiss were literate.
How long would it take to recite all the known digits of PI?
Infinitely long since there is an infinite number of digits.
Who were the first known people to value pi?
People from ancient civilizations knew about the value of pi but as it was then as it is now the exact value of pi has never been conclusively found because it is an irrational number.
Why is pi an inrational number?
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.
Who discovered pi first?
It is not known exactly who first discovered Pi. It has been used for over 4,000 years and dates back to the times of ancient Egyptians.
What is the history of pi?
pi has been around for as long as we have had written records.Its approximate estimated value of Pi up to 5 decimal places is 3.14159 .Archimedes was the first person to estimate the correct value of pi
How much of PI is known?
At one level a huge deal. Pi is known to an accuracy of the width of a hydrogen atom at the far end of the known universe. At the same time, since pi is an irrational number, it has an infinitely long decimal representation with no recurrence. So even if we knew 1 quadrillion digits of pi (we don't yet) we would only know one quadriliion infinitieth (to coin a word) of pi - that is 0%.
