The meaning of concentric circle is they have a common center.
So you can find the possible radii through the area to be covered.
The minimum area is 50 cm². You can find the radius by the formula
.
so the radius = 50÷r÷π=7.958 cm²
The maximum area is 60 cm². so the radius is 60÷r÷π=9.549 cm²
Since the circles should have common center, the possible radii is between 7.958 cm² and 9.549 cm².
