Think about how you line them up given the documentation. What conditions 
would have to hold in the constructor arguments for the circles' centers to be 
the same? What algebraic transformation do you have to perform?

To put it another way: What data does the constructor require to position a 
circle in a particular place? What data do you have available at the point of 
the constructor call? What formula transforms the latter to the former?
