If the perimeter of a circle is equal to that of a square, then the ratio of their areas is
(A) 22 : 7 (B) 14 : 11 (C) 7 : 22 (D) 11: 14
Answer(B) 14 : 11
Solution
According to question
(Because perimeter of circle = 2πr Perimeter of square =4 side)
(here side of square =a)
(Using area of square = a2)
Hence ratio of their areas is 14: 11
