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