    18.84

    Step-by-step explanation:

    the area is already stated so,

    28.26

    =

    π



    r

    2

    28.26

    π

    =

    r

    2

    8.995437

    =

    r

    2



    8.995437

    =

    r

    2.999239

    =

    r

    we have found that the radius is 2.999239 and the formula for circumference of a circle is:

    π



    d

    2.999239



    2

    =

    5.99848

    (multiply by 2 to get the diameter)

    5.99848



    π

    =

    18.84478

    so the answer is 18.84
