Solution

## The correct option is B π4 Given a circle is inscribed in a Square. If the length of the square is S As the circle is inscribed in the square. Therefore the diameter of the circle is exactly equal to the side of the square S. d=S Circumference of the circle =πd Circumference of the circle =π×S Now , Circumference of the CirclePerimeter of the square=πS4×S Circumference of the CirclePerimeter of the square=π4 Hence, the ratio of the circumference of the circle to the perimeter of square if the sides of the square were changed to S, remains unchanged equal to π4  Suggest Corrections  0      Similar questions  Related Videos   Circle Inscribed in a Square
