A square is inscribed in a circle. If the area of the square is 9 in2, what is the ratio of the circumference of the circle to t
IgorC [24]

The ratio of the circumference of the circle to the perimeter of the square is \pi \sqrt{2}:4

<em><u>Explanation</u></em>

Area of the square = 9 inch²

If the side length of the square is a, then

a^2 = 9 \\ \\ a= \sqrt{9} =3

So the side length of the square is 3 inch.

Now as the square is inscribed in a circle, so the diagonal of the square will be diameter of the circle.

Length of the diagonal of square = a\sqrt{2} = 3\sqrt{2} inch

So, the diameter of the circle = 3\sqrt{2} inch

If the radius of the circle is r, then

2r = 3\sqrt{2} \\ \\ r= \frac{3\sqrt{2}}{2}

Circumference of the circle, 2\pi r= 2\pi *\frac{3\sqrt{2}}{2}= 3\pi \sqrt{2} inch

and Perimeter of the square, 4a = (4*3)inch= 12 inch

So, the ratio will be: 3\pi \sqrt{2} : 12 = \pi \sqrt{2} : 4
