Question: What is the area of the sector Y?

To calculate the area of sector Y, we need the angles subtended by sector Y at the centre and the radius of the circle

Statement1: Area of the sector X is 2π.
Angle and radius of circle are missing

NOT SUFFICIENT

Statement 2: The diameter of the circle is [m]4\sqrt{3}
Radius is now known but angle subtended by Y at centre is missing

NOT SUFFICIENT

After combining the two statements
We can calculate the angle subtended by sector X
angle of sectorX + angle of sector Y = 180
i.e. now e know the angle of sector Y as well as the radius of sector Y hence

SUFFICIENT
