In the rectangular coordinate system on a plane, the parametric equations of curve $C$ are given by $\begin{cases} x=5\cos \alpha \\ y=\sin \alpha \end{cases}$ where $\alpha$ is a parameter, and point $P$ has coordinates $(3 \sqrt {2},0)$.
(1) Determine the shape of curve $C$;
(2) Given that line $l$ passes through point $P$ and intersects curve $C$ at points $A$ and $B$, and the slope angle of line $l$ is $45^{\circ}$, find the value of $|PA|\cdot|PB|$.
