If a circle has a circumference of 46 (PI sign) m, what is its diameter?
I don't understand what to do...and what the "m" is there for..
thanks for answering in advance =]

Firs the formula is:
C=(PI)*d [d=diameter, C= circumference, PI=3.14]
now you said 46 then the formula is
46=3.14*d
after that you just divide
46/3.14=d
and there you go, that's your diameter.

The m means meters, as everyone has said. The number pi (3.1415926535...) is _defined_ as the ratio of any circle's circumference to its diameter.
Therefore, if you have a diameter, you multiply by pi to get a circumference. If (as you do) you have a circumference, you divide by pi to get diameter.
46 * pi / pi = 46
And the answer is in the same units as the original value (since pi has no units).
46 m.

m = meters
circumference ( given by the you ) = 46 * pi
there is a formula for circumference
circumference = 2 * pi * radius = pi * diameter
therefore
46 * pi = pi * d
d = 46 * pi / pi
d = 46 m

m is meters, the unit of measurement so ur answer will be in meters
The formula for circumference is C=Pi x diameter

circuference is pi times diameter so the answer would be 46m. i dont know what th m is for, maybe meters but it doesnt change the answer..i hope!

Is it trying to indicate the number is expressed in meters?

maybe the m means meters

m is probably meters.
