    A square metallic frame has a perimeter of 208 cm. It is bent in the shape of a circle. Find the area of the circle (in square cm).

    1. 3567    
    2. 3444    
    3. 2345    
    4. 4532    

    hintHint:

    A equals   pi r to the power of 2 end exponent
    Circumference = 2×pi×r

    The correct answer is: 3444

      Perimeter of circle = perimeter of square
      2×pi×r = 208
      r = 33.12
      Area of circle = pi×r ×r = 3444.48 square cm.
