Question

    A wire is bent to form a square whose sides are of 88

    cm. If the same wire is bent to form a circle, then find the area (in cm2) of the circle formed.
    A 9826 Correct Answer Incorrect Answer
    B 9756 Correct Answer Incorrect Answer
    C 9856 Correct Answer Incorrect Answer
    D 9956 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Total length of the wire = 4 × length of the square = 4 × 88 = 352 cm So, circumference of the circle = 352 cm Radius of the circle = {352/(2π)} = {352 × 7/44)} = 56 cm Area of the circle formed = (22/7) × 56 × 56 = 9856 cm2
