The correct answer is 2r/π.
It is a 2D semicircular arc.
It is a 2D semicircular arc.

@Jay.
How do you know it's 2D semi-circular?
I think 4r/3π is correct.

4r/3π is correct because CG of the semi-circular arc is asked not semi-circular area.

CG of semi-circular arc is 2r/π.

Both semicircle (4r/3π) and semicircular arc (2r/π) are 2D the difference is that arc is basically a hollow semicircle it is like a wire making half perimeter of the circle only.
