    Answer:

    Circumference of a circle in terms of radius:

    Circumference = 2·π·r = 2·3.14·5 = 31.42 mm.(*)

    In terms of diameter:

    Circumference = π·d = 3.14·10 = 31.4 mm.(*)

    In terms of area:

    Circumference C = √4·π·A = √4·π·78.54 = 31.42 mm.(*)

    Step-by-step explanation:

    Note: For simplicity, the operations above were rounded to 2 decimal places and π was rounded to 3.14.
