    Answer:

    A≈254 cm^2

    Step-by-step explanation:

    The area of a circle is given by formula:  π
    r^2

    π  has a constant value of  3.14  And the radius of the circle is  9
    c
    m

    the area= π
    r^2 = 3.14 x (9)^2 cm^2

    =
    3.14
    ×
    (
    81
    )

    =
    254.34
