Answer 1

$\huge\underbrace\mathcal\pink{queStion}$

find the area of shaded part of the Fig. given below.

$\huge\underbrace\mathcal\pink{anSwer}$

The answer can be given by the sector whose center is A.

$\huge\underbrace\mathcal\pink{Solution}$

In part ABD,

Radius of the sector (r) = 7cm

Angle on the center (ϑ) = 90°

Area of the shaded part

= Area of the sector

$\frac{ϑ}{360} \pi {r}^{2} \\ = \frac{90}{360} \times \frac{22}{7} \times 7 \times 7 \\ = \frac{1}{4} \times 22 \times 7 \\ \frac{22 \times 7}{4} \\ = \frac{11 \times 7}{2} \\ = \frac{77}{2} \\ = 38.5 {cm}^{2}$
