what is the ratio for Pi

OpenStudy (anonymous):

i need all possible answers

OpenStudy (unklerhaukus):

one ratio some times used to approximate pi is π = 3.141592653589793.. 22/7 = 3.142857142857143.. its a good approximation

OpenStudy (unklerhaukus):

355/113 = 3.141592920353983 is a little bit better

OpenStudy (anonymous):

thanks but the question isn't looking for the number it's looking for stuff like C/(2r)

OpenStudy (unklerhaukus):

the exact ratio for pi is the ratio of the circumference to the diameter of a circle |dw:1370263622639:dw|

OpenStudy (anonymous):

ok so how do i find it on this graph

OpenStudy (unklerhaukus):

The radius is half the diameter |dw:1370263697296:dw|

OpenStudy (anonymous):

ok i got that

OpenStudy (unklerhaukus):

so what is pi in terms of radius?

OpenStudy (anonymous):

the letters are fmu if that's what you mean

OpenStudy (unklerhaukus):

π=d/C r=d/2 2r=d π=

OpenStudy (anonymous):

cool ill try those

OpenStudy (anonymous):

only one of those choices are up there

OpenStudy (unklerhaukus):

whops ** π=C/d

OpenStudy (unklerhaukus):

use this 2r=d into that↑ forumla

OpenStudy (anonymous):

i did thanks

OpenStudy (unklerhaukus):

what did you get?
