Question

    A wire is bent to form a square whose sides are of 44

    cm. If the same wire is bent to form a circle, then find the area (in cm2) of the circle formed.
    A 2464 Correct Answer Incorrect Answer
    B 2454 Correct Answer Incorrect Answer
    C 2474 Correct Answer Incorrect Answer
    D 2264 Correct Answer Incorrect Answer

    Solution

    Total length of the wire = 4 ├Ч length of the square = 4 ├Ч 44 = 176 cm So, circumference of the circle = 176┬аcm Radius of the circle = {176/(2╧А)} = {176┬а├Ч 7/44)} = 28 cm Area of the circle formed = (22/7) ├Ч 28┬а├Ч 28┬а= 2464 cm2
