6.

Explanation:

If you were to have a function, y=a*sin(bx)+cy=asin(bx)+c,
We know that:
The amplitude of the function is absa|a|.
The period of the function is (2pi)/b2πb
The mid-line of the function is cc.

Therefore, the bb in this function is pi/3π3.
(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!
