Question

Plz answer fast.....plz​

Answer 1

Explanation:

Area of sector is

$\frac{90}{360} \times \pi {r }^{2} \\ \frac{1}{4} \pi {r}^{2} \\ \frac{1 \times 36 \times 2}{4} \pi \\ 18\pi$

square inside circle having diagonal = radius=6√2

so 6√2=a√2

a=6

so length of sides of square=6

area of square=6×6=36

area of shaded region=area of sector-area of square

$18\pi - 36 \\ 56.52 - 36 \\ 20.52$

area of shaded region =20.52

hope it helps.......
