#### Answer

The period of $\sin{x}$ is $\pi$

#### Work Step by Step

The given graph shows the function $y=\sin{2x}$
As shown in the graph, the period is $2\pi$
To evaluate the period of $\sin{x}$, we note that the graph of $\sin{x}$ is compressed by 2.
So, the period of $\sin{x}=\frac{2\pi}{2}=\pi$
