Question

what is and how do you do the circumfernece

Answer 1

circumference is a fancy work for, the distance around a circle

Answer 2

how do you do it thoe

Answer 3

also, the definition of pi is such that: pi = C/d

therefore C = d pi

Answer 4

since the diameter of a circle is twice the raduis, some like to substitute 2r for d

C = 2 pi r

Answer 5

what school do you go too?

Answer 6

lol, saint leo university ....

Answer 7

i go too http/:www.connectionsacademy.com

Answer 8

connections academy

Answer 9

lots of our users seem to have online schooling

Answer 10

yep

Answer 11

what grade are you in?

Answer 12

once you graduate, "grade level" is rather pointless ....

Answer 13

have you graduated from math course, amistre?

Answer 14

ive passed many many math courses, yes. and ive even passed some that i have not even taken yet ...

Answer 15

what grade are you in @amistre64

Answer 16

i'm in the 6th grade

Answer 17

if i were to quantify a grade level .... then maybe the 36th grade?

Answer 18

oh

Answer 19

are you married

Answer 20

hahhaa

Answer 21

lol, lets stick to the question at hand. Do you understand the nature of circumference now?

Answer 22

no

Answer 23

i don't need the fromula i need to know how to do it

Answer 24

back when i was a kid, we would try to find the ratio of the distance around a circle as compared to its diameter. after many many attempts to define it as a rational number, it was determined that the ratio was indeed irrational. some greek guys then determined it cant be a number so they called it a letter, pi

Answer 25

i know that i don't need the fromula i need to know how to do it

Answer 26

do you have a boyfriend?

Answer 27

therefore the ratio of a circles outer length (circumference), to its diamter is equal to pi\[\pi=\frac Cd\]
since the radius of a circle is 2 times the diamter, d = 2r\[\pi=\frac C{2r}\]
therefore, \[C = 2\pi r\]

Answer 28

OMG!

Answer 29

why OMG!

Answer 30

why did you say OMG!

Answer 31

Whether you're designing a project, doing craft work, or you need to know how much fencing you should buy to go around that hot tub in the backyard, knowing how to find circumference of a circle can come in handy. In this article, you'll learn just how and the promise is that it's easy as pi!

Answer 32

because of your question 'do you have a boyfriend?'
you see this is learning site, not dating site...

Answer 33

go too heck

Answer 35

this tells all u need

Answer 36

lol :P @one_direction2002 looks like ur in good hands!!! these people are awesome helpers :)

Answer 37

if u need more explaining tag me or y friend godgavemeyou

Answer 38

its good to notice that since 2pi is also the measure of the radians of a circle, the length of any arc along a circle is simply\[Arc=\theta~r\]

Answer 39

huh @Pandalover485
