Formula to find circumference of quadrant?
Circumference of a circle = 2 * pi * r pi = 3.1415926535897932384626433832795 r= radius of circle Hence Circumference of a Quadrant = 2 * pi * r / 4 = pi * r / 2 = 0.5 * pi * r For more accurate value of pi, please refer: http://en.wikipedia.org/wiki/Pi
How is pi worked out?
Pi is the ratio between the circumference of a circle and its diameter. The first and most obvious way to find pi is to measure both the circumference and the diameter. This gives a very rough approximation. A second way is to use geometry. By fitting regular shapes with large numbers of sides both around and inside the circle we can narrow the boundary for the potential value of pi. The most accurate way to find pi is to do with its use in certain very complex formulae. Computers are required to determine pi to an infinite decimal place.
In math why does pi equal 3.14159262?
3.141592654 is probably more accurate but sometimes it is rounded off as 3.142 pi is an irrational number and its true value has never been determined even by the most powerful computers in the world because its decimal places runs into billions after billions after billions into infinity.
What does the ratio of the value of pi come from?
Any circle's circumference divided by its diameter has a value of pi
Is the Value of pi 3.19?

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 the most accurate fraction for pi?
Pi, being irrational, has an endless number of digits to the right of the decimal, as you know. But for almost any application, even basic engineering, a value of 3.1417 is highly accurate.
What scientist arrived at a fairly accurate calculation of the value of pi?
Archimedes
Where is pi found in a circle?
The value of pi is equal to the length of the circumference (outside edge) of a circle divided by its diameter (the distance across the circle, measured through its center) It turns out that this pi relationship is true for all circles. The value of pi is never precisely exact, but for all intents and purposes, 3.1415 is plenty accurate.
Who found the first known value of pi?
the founder of the longest pi is...
What is the example of truncation error?
Suppose you want to calculate the area of a circle with a radius of 10 cm.If you use pi = 3.14 the area will be calculated as 314 cm^2if, instead, you use pi = 3.145159, the area will be 314.5159 cm^2if you use pi, as used by Excel on my computer, you will get 314.159265358979 cm^2.If you use the most accurate value of pi (currently around 10 trillion digits) you will get a more accurate value of the area.The difference between the calculated value and the true value is the truncation value.
Where was pi found?
The value of pi is found by dividing the circumference of a circle by its diameter and pi is an irrational number which means it can not be expressed as a fraction.
What are the most accurate fraction for Pi?
355/113 = 3.141593
Can a measurement number be very accurate but not precise?
Yes. Take, for example, the value of Pi. Pi is defined as the decimal equivalent of 22/7. 22/7 done manually is 3.142857 - which is accurate for most calculations. However - calculated by a computer, a more precise value can be obtained... The calculator built-in to Windowws produces the result 3.1415926535897932384626433832795
