Answer 2

Answer:

$area \: of \: the \: shaded \: region \: = \frac{ {\pi \: r_{1}}^{2} }{2} + 2 \times \frac{ {\pi \: r_{2} }^{2} }{27}$

$= \pi( \frac{ {r_{1}}^{2} }{2} + { r_{2} }^{2} )$

$= \pi ( \frac{ {20}^{2} }{ {2}^{2} } + {7}^{2} )$

$= \pi( \frac{400}{4} + 49)$

$= \pi(100 + 49)$

$= \frac{22}{7} \times 149$

$= 468.286 \: ......(aprox)$

I Hope It Will Help!
