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.

What does pi pi sili evolve into?
pi pi sili evolves into pi pi 1st in the mulecular pi industry. But if you subtract the remaining sili, it evolves into the 67th multivrese. but if its pi day, it would evolve into 2.57
What is pi minus pi?
pi minus pi is zero. Any number minus itself is zero.
What is pi plus pi?
pi+pi is 6.28. all that you have to do is add up the numbers.-fromama fromamzez.webs.com
What is the circumference of the circle in terms of pi?
pi = circumference/diameter circumference = pi*diameter or 2*pi*radius
What is pi squared to the one half power?
it is pi..... wait no it isnt.....pi squared to the one half power is not pi...
Why is pi not a rational number?
That's just the way it worked out. Pi is the ratio of the circumference of a circle to its diameter, and it just worked out that this ratio is an irrational number.
What American mathematicians worked with pi?
James Gregory
Who first worked out pi?
Jacob Galasso in 1744
What number did egyptians first used for pi?
The ancient Egyptian worked out the value of pi as being 3.16
Who worked out a value for pi using a ninety-six sided regular polygon?
Euclid discovered pi
Which scientist evualuted the pi value?
Lots of scientists have worked on evaluating pi. The question needs to be a little ,ore specific.
How was the value of pi ditermined?
The value of pi is determined by dividing a circle's circumference by its diameter and an exact value has never been worked out because pi is an irrational number.
What do you multiply to get the circumference?
The circumference of a circle is worked out by multiplying the diameter of the circle by pi.
What is Pi signify?
Pi is the ratio of the circumference of a circle to it's diameter . That is, Pi=C/d.It is expressed as the rounded irrational number 3.1415 That is Pi to four places. It has been worked out to four millionplaces - and that's still not it exactly.
What is PI exactly equal to?
3.14159265 ............ then possibly to infinity It's never been worked out exactly.
When was the area of the circle invented?
The exact area of a circle has never been worked out because the value of pi in the area of a circle which is pi times radius2 is only an approximation.
Can a circle have perimeter?
Circles do have a perimeter, which is known as the circumference. The circumference is worked out by multiplying:2, Pi, Radius (r)Pi, Diameter (d)Hope that's helpful for you!
