Question 923537
<pre><font size=4><b>
The question is:
How many of these:  {{{drawing(400,400,-14,14,-14,14,rectangle(-5,-5,5,5),
locate(0,-5,10cm)
)}}}

will fit in one of these?:  {{{drawing(400,400,-14,14,-14,14,circle(0,0,6.5),
green(line(-6.5,0,6.5,0)),locate(0,0,13cm)
 )}}}

We can easily see just by looking at the size of them that more than 1 
of them but a lot less than 2 of them will fit in there.

The area of the 10cm by 10cm square is  A = s<sup>2</sup> = (10cm)<sup>2</sup> = 100cm<sup>2</sup>.

The area of the 13cm diameter circle, which has radius {{{(13)/2}}}cm, is
A = <font face="symbol">p</font>r<sup>2</sup> = {{{pi*(expr(13/2)cm)^2}}} = {{{pi*(169/4)cm^2}}} = {{{expr(169pi/4)cm^2}}} = 132.7322896 cm<sup>2</sup>

Dividing 132.7322896 by 100 we get 1.327322896 of the squares will fit
inside the circle,

So not quite {{{1&1/3}}} of those squares will fit in that circle.
