circumference = 2 x pi x radius which is the same as pi x diameter so the answer is pi.
There have been many estimations of Pi by many scientists over the years. To answser this questions, more information is needed. You might also see the link on the history of Pi.
None. There is no problem!
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'.
A 24-foot circle has a circumference of 24' x Pi or 75.36 feet, using 3.14 for Pi.
There are no degrees in pi, it is a ratio.
there are infinite numbers in pi
Pi = circumference/diameter
there are 29 7's in pi
Generally pi is shown as 3.14, but realistically pi continues on forever.http://en.wikipedia.org/wiki/Pi
So far no one has found the end of pi. Many people round it to 3.14. Because pi does not have an end (that we know of) any answer using pi is only approximate.
There is no end to the number pi...it goes on indefinately. However, pi to the 2oth place is 3.14159265358979323846.
The only one that I am aware of is the greek letter pi: π. There are many approximations, such as 3.14 or 3.14159 or 22/7. There are many functions whose solutions involve pi and so can be used to calculate pi. There are also many infinite series that converge to pi or some function of pi. Some are given in the attached link. However, these are all approximations to pi.
There are infinitely many. For example: (17+pi) and (10-pi)
Since pi is irrational , so the answer is infinity.
Alpha Pi Sigma has many calls.
Pi is the ratio of the circumference of a circle to its diameter. Pi is 3.1415926535897932384626433832795 but some just use 3.14
