Question

Find the area of the sector in given diagram.​

Answer 1

Answer:

Angle of sector = 60°

Radius of circle = 4 cm

Area of the sector,

$= \frac{60}{360} .\pi {r}^{2}$

$= \frac{1}{6} . \frac{22}{7} .16$

= 8.38 Sq cm

Answer 2

Step-by-step explanation:

$radius \: of \: circle= 4 \: Cm \\ \theta = 60\degree \\ area \: of \: sector = \frac{ \theta}{360 \degree} \times \pi {r}^{2} \\ = \frac{60 \degree}{360 \degree} \times \frac{22}{7} \times {4}^{2} \\ = \frac{1}{6} \times \frac{22}{7} \times 16 \\ = \frac{22 \times 8}{3 \times 7} = \frac{176}{21} = 8.38 \: {cm}^{2}$
