circumference = (pi)* Diameter
or
(pi)= circumference*Diameter

not that complicated...

Pi does not equal circumference*Diameter
Pi=Circumference/Diameter

This post is about why pi = 3.14, not calculating circ. *ducks*
User avatar #453 to #451 - jurassicparkerr (06/02/2012) [-]
The post is EXACTLY the second equation. Assuming the diameter is 1, the diameter is 3.141296539 etc.

The better question: WHY is it that way?
#477 to #447 - anon (06/02/2012) [-]
Because the diameter goes 3.14 times around the cirkle. Noob
User avatar #452 to #447 - krazeeguitarist (06/02/2012) [-]
Because like most mathematics "pi" is based on the unit circle ( of dimensions r=1)
#461 to #447 - paradoxpoetic (06/02/2012) [-]
Pi is the circumference of a circle (the outside line) divided by the diameter of the circle (a direct line from one end, passing through the middle, to the opposite side). Every circle has the ration of circumference to diameter the same, which is why Pi is such an important number in math. Or one of the reasons, at least.
User avatar #593 to #461 - ihadtoregister (06/03/2012) [-]
I know that, I've taken geometry. But why 3.14159? Why not 2.8943? Or 4.2756?
#595 to #593 - paradoxpoetic (06/04/2012) [-]
Pi is basically a fraction. Let C = Circumference, D = Diameter. So Pi is C / D or C : D, depending on if you want a fraction or a ratio. The ratio of C : D will always give the same answer because, as C changes, so does D. C : D will always result in the same answer. It's the same as taking a square, and dividing the length of side A by the length of side B. You will *always* get 1. Whether the square has lengths of 100 inches or 1000 inches, it will always be the same. Now this isn't an exact number, but the generally accept rounded estimate of pi is about 22/7. Meaning a circle with a circumference of 22 will have an estimated diameter of 7. If the circle has a circumference of 44, the estimated value of the diameter would be about 14. The reason it's 3.14159... is because that is simply what it comes to. We signify it with a name and symbol because Pi is an important ratio involved in a lot of more difficult math involving circles, etc... And it reoccurs frequently.

I hope I answered your question. If not, I'm afraid I don't understand what you're asking.

This was the closest you got to answering my question: "The reason it's 3.14159... is because that is simply what it comes to."

But that was a really good explanation of it. I get that it's a ratio, but I just wonder why that number of all numbers is what it comes to. It's quite a weird number. :)
#597 to #596 - paradoxpoetic (06/04/2012) [-]
It's the same reason why an equilateral triangle has three 60 degree angles, or even the same reason as 1 + 1 = 2. It's just the answer to the question. really. Every perfect circle has the same answer for C : D, which is Pi, and that odd number just happens to be the answer to Circumference / Diameter. I'm sorry if that seems a little... underwhelming, but it is what it is.

Did people not actually know where pi came from? What kind of education system does America have?

im in algebra 2 and i had no idea where it came from. teachers just said it came from circles

Most american school systems nowadays focus so much on keeping things like drugs and alchohol by putting all their funding and time into "SAY NO 2 DRUG, 1 MARYJANE CIGRETT WORS DEN 2 PAK OF CIGGRETT," campaign ******** , which is the job of the parents to keep their bratty ass ************* in line, they can't hire decent teachers to teach anymore. One teacher at my old school didn't even have a degree. The only disciplinary things teachers can do to attempt to keep the ************* in line is throw them out of the class or call the parents, who most of the time are just as bad as the kids, so they give zero ***** .
Even the decent teachers can't teach because of the campaign ******** pulls students out of classes, taking away valuable class and teaching time.
I am an American 9th grader, (14-15), so I have experienced all of this first hand.

I agree 100%, Just one or two would be fine.   
all through my 6th grade year, (11-12 yrs old.) They had this Officer of teh law come in EVERY thursday, take up a whole science period, and teach me nothing but 			****		 I already knew because I'm not a brainless 			**********		.   
And we had to complete this dumbass workbook filled with the same propaganda about how Marijuana is the worst thing in the world.   
Also had to write a 5 paragraph essay, That's a lot when you're only 12, about what you learned from the whole 			******		 year of the anti-drug 			****		, and why you won't do drugs in the now and in the future.   
But that brings me back to my next point, it doesnt affect anything in the 			**************		 mind.   
In 8th grade (13-14), my neighbor, who also had to go through that anti-drug thing, was caught smoking Marijuana at school. Which just proves it's the parents who affect the kids behavior around drugs, and how well the decisions they make are. Especially because her mother is a whore (5 "boyfriends" in a 4 month span, and 5 diff. kids from 3 different baby daddys.")

just sarcasm. probably wasn't very clear on that. oh well.

Can you seriously not pick up the sarcasm here? Someone needs to invent a sarcasm font because apparently being blatantly obvious isn't enough.

I've started using italics as my sarcasm font. It works, except most of my messages that need it are text so it can't be used,

Pi is the ratio of the circumference to the diameter. This is just an illustration of circumference.

Pi = 3.14.

He took a circle and stretched out a line that was around it into a straight path. The line ended at 3.14 exactly if you look closely. you can do this with any circle because it will always end at 3.14. If you do this with a 1 inch in diameter circle, you can see that it will end at 3.14 inches. :D
#270 to #258 - anon (06/02/2012) [-]
Actually Pi is an infinite number..
#277 to #270 - anon (06/02/2012) [-]
No, my good sir. It's the digits that are infinite. While the number itself hovers just over 3.
User avatar #272 to #270 - TheSpartanHelghast (06/02/2012) [-]
Ah. Excuse me. I don't know that much about math and stuff. Lol. Thanks anon! You are helpful.
