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

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

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):
