    Question

    A wire is bent to form a square whose sides are of 22

    cm. If the same wire is bent to form a circle, then find the area (in cm2) of the circle formed.
    A 606 Correct Answer Incorrect Answer
    B 626 Correct Answer Incorrect Answer
    C 616 Correct Answer Incorrect Answer
    D 646 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Total length of the wire = 4 ร— length of the square = 4 ร— 22 = 88 cm So, circumference of the circle = 88 cm Radius of the circle = {88/(2ฯ€)} = {88 ร— 7/44)} = 14 cm Area of the circle formed = (22/7) ร— 14 ร— 14 = 616 cm2
