6.

Explanation:

If you were to have a function, #y=a*sin(bx)+c#,
We know that:
The amplitude of the function is #absa#.
The period of the function is #(2pi)/b#
The mid-line of the function is #c#.

Therefore, the #b# in this function is #pi/3#.
#(2pi)/(pi/3)=>2cancelpi*3/cancelpi=>6#
The period is 6.
graph{sin(pix/3) [-10, 10, -5, 5]}
In our graph here, we see that 6 is indeed the period.

It is important to know why this works!
