Answer

$Amplitude$ $=$ $3$ $Period$ $=$ $\pi$

Work Step by Step

The highest point (amplitude) in the graph is at $y = 3$ $Divide$ $the$ $natural$ $period$ $of$ $a$ $sine$ $wave$ $2π$ $to$ $the$ $coefficient$ $of$ $x$ $inside$ $the$ $trigonometric$ $function$: $Period$ $(T)$ $=$ $\frac{2\pi}{2}$ $=$ $\pi$
