    The distance around a rectangle or a square is as you might remember called the perimeter.

    The distance around a circle on the other hand is called the circumference. It is calculated as follows:

    C = 2pi (r)

    From this, we can solve for r and eventually solve for the diameter.

    44 = 2pi (r)

    r ≈7.00

    d = 2r

    d = 142answers
