    Well the formula for circumference of a circle is either\[2\Pi r\] or \[\Pi d\]

    So if you have a circumference of 4pi, plug it in to get \[4\Pi = \Pi d\]

    d is diameter by the way

    No because all you have to do is divide each side by \[\Pi \] to get \[4=d\]

    No, the circumference is equal to the diameter times pi. If you have a circle with diameter of 6, then multiply the diameter times pi. Your circumference is 6pi

    So I think you're thinking about this the hard way. Just think about plugging the circumference into a formula and solving for an answer. If the formula is \[C=\Pi \times d\] just plug in the number you have for C and then solve for d

    The number you have is \[4\Pi \] so plug that in for the variable C

    Of course I'm glad you get it!
