Answer 1

Step-by-step explanation:

Area of shaded region = Area of larger semicircle - Area of circle - 2(Area of small semicircle) + Area of small semicircle

= Area of larger semicircle - Area of circle - Area of small semicircle

= [π(4.5 cm)²/2] - π(4.5/2 cm)² - [π(3/2 cm)²/2]

= π[(4.5)²/2 - (4.5/2)² - (3/2)²/2] cm²

= 12.37 cm²

Answer 2

Answer:

$\mathcal\red{Area\:of\:sehaded\: reason}$

=Area of larger semi circle

Area of circle -2(Area of small circle)+

Area of small semicircle

=Area of larger semicircle - Area of circle - Area of small semicircle

=

$|\pi(4.5cm {}^{2} ) \div 2 | - \pi(4.5 \div 2cm {}^{2} ) - |\pi(3 \div 2) {}^{2} \div 2|$

-[π(3/2cm²/2)]

= π(4.5)²/2-(4.5)/2²-(3/2)²/2]cm²

$12.37cm {}^{2}$
