Heya mate!!

$area \: of \: circle = \pi {r}^{2}$

$\frac{22}{7} \times 28 \times 28$

$2464 {cm}^{2} \\ area \: of \: 1 \: square = 8 \times 8 = 64 {cm}^{2}$

$area \: of \: 30squares = 8 \times 8 = 64 {cm}^{2}$

$area \: of \: shaded \: region = 2464 - 1920 = 544 {cm}^{2}$

Hope it helps you dear✌️✌️
