Thank you very much. Answer by ikleyn(52781) (Show Source):
Since the radius of the smaller circle is cm (given), it means that the distances
from its center to x- and y-axes are equal to r = cm.
Hence, the center of the small circle is at the distance d = = 2 cm
from the origin of the coordinate system.
It implies that the radius of the large circle is R = cm.
Hence, the area of the large circle is option C).
