$\huge\mathfrak\red{Solution}$

$<b>$

The area of path = the area of circle including path - the area of circle excluding path.

$area \: of \: path = \pi {r}^{2} - \pi {r}^{2} \\ (here \: r \: is \: different)$

$= \frac{22}{7} \times 33 \times 33 - \frac{22}{7} \times 30 \times 30 \\ = \frac{23958}{7} - \frac{19800}{7} \\ = \frac{23958 - 19800}{7} \\ = \frac{4158}{7} = 594 {cm}^{2}$

The area of path =594 cm2
