Question 1065051
.
A square is inscribed in a circle. If the area of the square is 9 in squared, what is the ratio of the circumference of 
the circle to the area of the circle?
~~~~~~~~~~~~~~~~~~~~~~~~~~~


<pre>
The ratio of the the circumference of the circle to the area of the circle is

{{{(2*pi*r)/(pi*r^2)}}} = {{{2/r}}}.


We are given {{{a^2}}} = 9.


Hence, a = 3.


Therefore,  r = {{{(a/2)*sqrt(2)}}} = {{{1.5*sqrt(2)}}}.


Then the ratio of the circumference of the circle to the area of the circle is {{{2/(1.5*sqrt(2))}}} = {{{sqrt(2)/1.5}}} = {{{(2*sqrt(2))/3}}} {{{1/in}}}.
