    circumference = 12.56 m.

    Step-by-step explanation:

    circumference of a circle is the distance around the circle or the perimeter of the circle.

    the diameter is two times the radius

    d = 2 r

    circumference = 2 π r = π (2r) = π d

    Given: diameter = d = 4 and π = 3.14

    ∴ circumference = 4 * 3.14 = 12.56 m
