    Question

    A wire is bent to form a square whose sides are of 66

    cm. If the same wire is bent to form a circle, then find the area (in cm2) of the circle formed.
    A 5544 Correct Answer Incorrect Answer
    B 5524 Correct Answer Incorrect Answer
    C 5144 Correct Answer Incorrect Answer
    D 5044 Correct Answer Incorrect Answer

    Solution

    Total length of the wire = 4 × length of the square = 4 × 66 = 264 cm So, circumference of the circle = 264 cm Radius of the circle = {264/(2π)} = {264 × 7/44)} = 42 cm Area of the circle formed = (22/7) × 42 × 42 = 5544 cm2
