Question

find the area of sector of a circle with radius 21 cm. if angle of the sector is 60 degree​

Answer 1

➸ Given:-

• Radius of Circle = 21.
• Angle of the sector = 60°

➸ To Find:-

• Area of Sector.

ᬊ Required Response:-

$\boxed{\sf{Area\;of\; Sector = (\frac{\theta}{360°})\pi{r}^{2}}}$

$( \frac{60}{360} ) \times \frac{22}{7} \times {(21)}^{2} \\ \frac{1}{6} \times \frac{22}{7} \times 21 \times 21 \\ \frac{(22 \times 21)}{6} \\ 77$

Area of Sector

• $\longmapsto\;\red{\bold{77{cm}^{2}}}$
