There is a square of side 6cm . A circle is inscribed inside the square. Find the ratio of the area of circle to square.
Select the correct option:
A) 11 / 14
B) 1 / 14
C) 13 / 14
D) 12 / 14
E) 5 / 14

Rationale: let the side of square = a unit so area of square = a ^ 2 diameter of inscribed circle = side of square = a radius of circle = a / 2 area of circle = ( 22 / 7 ) ( a / 2 ) ^ 2 ratio of area of circle to square = { ( 22 / 7 ) ( a / 2 ) ^ 2 } / a ^ 2 = 11 / 14 answer : a
Answer: A
