    A wire is bent to form a square whose sides are of 33

    cm. If the same wire is bent to form a circle, then find the area (in cm2) of the circle formed.
    A 1385 Correct Answer Incorrect Answer
    B 1366 Correct Answer Incorrect Answer
    C 1386 Correct Answer Incorrect Answer
    D 1286 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Total length of the wire = 4 Ă— length of the square = 4 Ă— 33 = 132 cm So, circumference of the circle = 132 cm Radius of the circle = {132/(2Ď€)} = {132 Ă— 7/44)} = 21 cm Area of the circle formed = (22/7) Ă— 21 Ă— 21 = 1386 cm2
