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)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
