$\huge\boxed{\mathfrak{\underline{\underline{\red{\star QUESTION}}}}}$

The boundary of the shaded region in the given figure consists of three semicircles, the smaller being equal. If the diameter of the larger on is 28 cm, find

(i) the length of the boundary

(ii) the area of the shaded region.

$<marquee scrollamount="20">(i) answer</marquee>$

$= \frac{22}{7} = (14 + 2(7) \\ = \frac{22}{7} \times 28 = 4 \\ = 88$

$<marquee scrollamount="20">(ii) answer</marquee>$

$\pi \: {r}^{2} \\ = \frac{22}{7} \times 14 \\ = 22 \: \times 2 \\ = 44 \times 4 \\ = 176$
