    The circumference of the round pizza is 21.26in

    Step-by-step explanation:

    To solve this exercise we first have to calculate the radius of the circle, for this we will use the formula of area of a circle and we will clear the radius

    a = area = 36in²

    r = radius

    π = 3.14

    a = π * r²

    we clear r

    r = √ (a/π)

    now we replace the known values

    r = √ (36in²/3.14)

    r = √ (11.46in²)

    r = 3.385 in

    now we use the formula to calculate the circumference of a circle

    c = π * 2r

    c = 3.14 * 2 * 3.385 in

    c = 21.26in

    The circumference of the circle is 21.26in
