Right triangle ABC has AB = AC = 6 cm. Circular arcs are drawn with centers
at A, B and C, so that the arc centered at A is tangent to side BC and so that the
arcs centered at B and C are tangent to the arc centered at A, as shown. What is
the area of the shaded region inside AABC but outside the three arcs? Express
your answer as a decimal to the nearest hundredth.
