    Answer: (4) 98.56 cm2

    Explanation:-
    The circumference of a circle = 35.2 cm

    Formula-
    The circumference of the circle = 2 pai r

    Then, 2 pai r = 35.2
    r = 35.2/2 pai
    r = 17.6 x 7/22
    r = .8 x 7
    r = 5.6 cm

    Formula-
    The area of the circle = pai r2
    then, the area of the circle = 22 x (5.6)2/7
    = 22 x 5.6 x 5.6/7
    = 22 x .8 x 5.6
    = 98.56 cm2
    Then, the area of the circle is 98.56 cm2.

    Hence, the answer is (4) 98.56 cm2.
