    The circumference of a circle can be found by multiplying pi ( π = 3.14 ) by the diameter of the circle.

    If a circle has a diameter of 4, its circumference is 3.14*4=12.56

    If you know the radius, the diameter is twice as large.

    Circumference = 2 • π • radius = 2 • π • 12 = 75.39 = 75.4
