The question is:
How many of these:  

will fit in one of these?:  

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 = s2 = (10cm)2 = 100cm2.

The area of the 13cm diameter circle, which has radius %2813%29%2F2cm, is
A = pr2 = pi%2A%28expr%2813%2F2%29cm%29%5E2 = pi%2A%28169%2F4%29cm%5E2 = expr%28169pi%2F4%29cm%5E2 = 132.7322896 cm2

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

So not quite 1%261%2F3 of those squares will fit in that circle.

If you mean the tiles are 10 by 10 cms, the diagonal of the square is 10*sqrt(2) =~ 14.14
Unless there's some cutting, zero.
=============
If you meant the area of the tiles is 10 sq cm, post again.
