      Question

      The ratio of the length of a rectangle, breadth of the

      rectangle and the diameter of a circle is 14:5:7. If the area of the circle is 616 cm2 , then what is the difference between the circumference of the circle and the perimeter of the rectangle?
      A 64 cm Correct Answer Incorrect Answer
      B 60 cm Correct Answer Incorrect Answer
      C 69 cm Correct Answer Incorrect Answer
      D 61 cm Correct Answer Incorrect Answer
      E None of these Correct Answer Incorrect Answer

      Solution

      Area of the circle = ฯ€r2 616 = 22/7 ร— r2 r2 = 196 r = 14 cm (Since, radius cannot be negative) Radius of the circle = 14 cm Diameter of the circle = 2r = 28 cm Length of the rectangle = (28/7) ร— 14 = 56 cm Breadth of the rectangle = (28/7) ร— 5 = 20 cm Perimeter of the rectangle = 2 ร— (56 + 20) = 152 cm Circumference of the circle = 2 ร— (22/7) ร— 28 = 88 cm Required difference = 152 โ€“ 88 = 64 cm
