Pls help 7th-grade math

Answer 1

Answer:

Area of shaded region is equal to area of circle - Area of rectangle

Area of circle = πr^2

= 22/7×12×12

= 3168/7 cm^ 2

Area of rectangle

= 10×3 = 30 cm^2

Area of shaded region now

$\frac{3168}{7} - 30 \\ \frac{3168 - 210}{7} \\ \frac{2958}{7} = 422.57 ....cm \: sq$
