    Question

    The circular field has a perimeter (circumference) of

    264 meters. Calculate the area of the field. {Take π = (22/7)}
    A 3850 sq m Correct Answer Incorrect Answer
    B 5544 sq m Correct Answer Incorrect Answer
    C 3950 sq m Correct Answer Incorrect Answer
    D 4455 sq m Correct Answer Incorrect Answer

    Solution

    Let the radius of the circular field = 'r' metres Then, circumference of the field = 2 X π X r = 2 X (22/7) X r Or, (44r/7) = 264 So, r = (264 X 7) ÷ 44 = 42 So, area of the field = π X r2 = (22/7) X 422 = 5544 cm2
