    Answer: (3) 154 cm²

    Explanation:-
    Formula –
    The circumference of a circle = 2 π r

    Then, the 2 x 22 x r/7 = 44
    r = 7

    Formula –
    The area of the circle = π r²

    Then, the area of the circle = 22 x 7 x 7 /2
    = 22 x 7
    = 154 cm²

    Then, the area of the  circle is 154 cm².

    Hence, the answer is (3) 154 cm².
