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.
Is the Value of pi 3.19?
no, 3.1415926535897932384626433832795028841971693993751058209749445923078164062862089986280348253421170679 8214808651328230664709384460955058223172535940812848111745028410270193852110555964462294895493038196 4428810975665933446128475648233786783165271201909145648566923460348610454326648213393607260249141273 724587006606315588174881520920962829254091715364367892590360011330530548820466521384146951941511609...
What does the ratio of the value of pi come from?
Any circle's circumference divided by its diameter has a value of pi
