Question

Find the area of shaded region

Answer 1

Step-by-step explanation:

Area of shaded region = area of semicircle-area of circle

let the radius of semicircle be n and radius of circle be m

$\frac{\pi {n}^{2} }{2} - \pi {m}^{2}$

n=2m,from fig. diameter of circle is radius of circle

n=2×4=8

$\frac{22}{7 \times 2} \times 8 \times 8 - \frac{22}{7} \times 4 \times 4$
