Is the area of circle X greater than the area of circle Y?

(1) The circumference of circle X is greater than the circumference of circle Z, and the circumference of circle Z is less than the circumference of circle Y.

(2) The radius of circle X is greater than the radius of circle Y.

Kudos for a correct solution.

I have seen a similar question in number format --- whether the underlying concept is similar --- only here they have changed it into geometry .This how Gmat works i guess .

St . 1 is not sufficient .

radius of X = x

radius of Y =y

radius of Z =z

2pie x > 2pie z

and

2pie z < 2pie y

There is no relation between x and y . Hence not sufficient .

St 2.

radius of X = x

radius of Y =y

radius of Z =z

x > y

If radius of x is more than y . Then area of x will definitely more than y .

B ans .
