Question

    A wire is bent to form a square whose sides are of 132

    cm. If the same wire is bent to form a circle, then find the area (in cm2) of the circle formed.
    A 22176 Correct Answer Incorrect Answer
    B 23176 Correct Answer Incorrect Answer
    C 25176 Correct Answer Incorrect Answer
    D 26176 Correct Answer Incorrect Answer

    Solution

    Total length of the wire = 4 × length of the square = 4 × 132 = 528 cm So, circumference of the circle = 528 cm Radius of the circle = {528/(2π)} = {528 × 7/44)} = 84 cm Area of the circle formed = (22/7) × 84 × 84 = 22176 cm2
