Answer
$(3, 0)$
Work Step by Step
The conversion of rectangular coordinates $(x,y)$ to polar coordinates $(r, \phi)$ can be computed as:
$r=\sqrt{x^2+x^2}$ and $\theta=\tan^{-1}(\dfrac{y}{x})$
We have: $r=\sqrt{3^2+0^2}=3$
and $\theta=\tan^{-1}\left(\dfrac{0}{3}\right)=0$
Therefore, the point $(x,y)$ has coordinates $(3, 0)$ in the rectangular coordinate system.
