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)
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 14 : 11
Side of square = Diameter of circle
Let, side of square is x and radius of circle is r
x = 2r
⇒ x/r = 2
Area of square/Area of circle = x2/πr2 = (x/r)2 × 7/22 = 22 × 7/22 = 14/11
Required ratio = 14 : 11
