      Question

      The ratio between the area of a square and that of a

      circle, when the length of a side of the square is equal to that of the diameter of the circle, is (take π = 22/7)
      A 14 : 11 Correct Answer Incorrect Answer
      B 28 : 11 Correct Answer Incorrect Answer
      C 7 : 22 Correct Answer Incorrect Answer
      D 22 : 7 Correct Answer Incorrect Answer

      Solution

      Let the diameter of the circle and sides of the square be 14 cm, then   The radius of the circle r = 14/2 = 7 cm Side of the square a = 14 cm As we know, Area of square = a² Area of circle = πr² Ratio of area of the square to that of circle = 142: 22/7 × 7 × 7   = 14:11
