St1) figure is not restricted. Various sizes circle are possible with varying common overlaps. Another way to think is count information is asked but ratio information is given.
Not suff.
St2) various radius can give 36pi as area of unshaded region. So overlap will keep on changinh.
Combining: the radius is restricted and unshed area is restricted. So only one unique value of common overlap exist
Answer seems C
Thank you = Kudos
