@Lydia_S. I think these questions are a bit vague...
could you please be more specific as to what you mean and what info is given?

I don't really have anymore info.. :((  That was just what I'm supposed to know for my TerraNova test.

"area of a circle withing a circle"
if you know the radius or diameter or circumference of the inner circle that is all you need

I'm not sure what other context they may ask you this in....

you don't mean the area between two circles?
