Question 768706
{{{drawing(400,1000/3,-1,11.6,-1,9.5,
circle(5.3,4.25,4.25),locate(5.3,0,10.6cm),locate(10.7,4.3,8.5cm), 
rectangle(0,0,10.6,8.5) )}}}
<pre>
Draw in the diameter from top to bottom of that circle,
in green below:

{{{drawing(400,1000/3,-1,11.6,-1,9.5,green(line(5.3,0,5.3,8.5)),
circle(5.3,4.25,4.25),locate(5.3,0,10.6cm),locate(10.7,4.3,8.5cm), 
rectangle(0,0,10.6,8.5) )}}}

The green diameter is the same as the shorter side of the
rectangle.  So the radius of the circle is {{{1/2}}} the diameter or 
{{{1/2}}}{{{""*""}}}{{{8.5}}} = 4.25 cm.

Area of a circle = <font face="symbol">p</font>r<sup>2</sup> = (3.14)(4.25)<sup>2</sup> = 56.71625 cm², rounded to tenth of a square centimeter,

Answer = 56.7 cm²
