What do you mean 'finding'?
Pi is the ratip of the circumference to the radius of a circle.
6(pi)l2, where l = length of side
C = 2∏r is the formula for calculating the circumference of a circle
Formula for calculating the area of a hemisphere... Area = (4 x pi x r2) / 2
Yes. There are several, but some are "hard to use" or "hard to understand" and some other ones, particularly the "simple and easy" ones take a lot of work (a lot of steps) to derive "the next digit" in the sequence. Use the link to the Wikipedia article on calculating the value of pi and see what you think will work for you. If push comes to shove, there is software that will turn your PC into a pi computing machine. Need a link to the Wikipedia article? You got it.
The area of a sphere is 4 (pi) (radius)2. The area of 1/2 of the sphere is 2 (pi) (radius)2. If you want to add in the flat end of the hemisphere, that makes the total surface area 3 (pi) (radius)2.
Archimedes was the first Western mathematician to make a serious attempt at calculating the value of pi. His estimated, that pi was between 3.1408 and 3.1429.
Yes and it is for any circle: circumference/diameter = pi

4 * pi * r * r15 Fby subcooling20The formula for calculating the area of a circle - is Pi x r x r
Formula for calculating the area of sphere is : 4 * pi * r * r
Archimedes (287-212 BC) was the first to have had a serious attempt at calculating pi.
Pi is an irrational number, which means that it goes on forever without repeating. So I can't really give you the exact value. However, there are several ways of calculating pi. in terms of a circle: Pi = Circumference/Diameter for more complicated ways of calculating pi, I would suggest looking at the wikipedia page http://en.wikipedia.org/wiki/Pi

2,,r or ,,d 2x pi x radius or Pi x Diameter
Pi has undoubtedly contributed to math. Pi can be used for calculating circles and was used to measure distances without doing it the harder way....
pi is defined as circumference divided by diameter circumference = pi * diameter pi is approximately 3.14159...... non-repeating, never ending decimal places
Take the diameter of the circle times 3.14159 (which is PI).
