A circular floor with radius $28 c m$ is tiled with $30$ square tiles of side $8 c m$ as shown figure. Find the area of the shaded region.

Open in App

Solution

Area of shaded region $=$ area of circle $-$ area of square tiles

$⟹ π \times 28 c m \times 28 c m - 30 \times (8 c m)^{2}$

$⟹ 2463.009 c m^{2} - 1920 c m^{2}$

$⟹ 543.009 c m^{2}$
