    12

    Step-by-step explanation:

    The circumference of a circle is given as

    Circumference = 2πr

    Where; r is the radius of the circle

    The diameter of a circle is 2 times the radius of that circle. It cuts the circle into 2 equal halves

    Given, circumference of the circle = 12π

    12π = 2πr

    make r the subject by dividing both sides by 2π

    12π/2π = 2πr/2π

    r = 6

    Diameter = 2r

    = 2 X 6 = 12
