there is a square of side 6 cm . a circle is inscribed inside the square . find the ratio of the area of circle to square .
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
divide(circle_area(divide(6, const_2)), square_area(6))
