Question

Find the area of the sector of a circle with radius 21 cm and of angle 60°​

Answer 1

$\Large{\underline{\underline{\sf{Given:}}}}$

• Radius of Circle = 21cm
• Angle between the radii and an arc at centre is 60°

$\Large{\underline{\underline{\sf{To\; Perceive}}}}$

• Area of Sector.

$\Large{\underline{\underline{\sf{Required\; Response}}}}$

Area of Sector = $\frac{ \alpha }{360} \times \pi {r}^{2}$

At Which, $\alpha$ be the angle.

$\frac{60}{360} \times 3.14 \times {21}^{2}$

$6 \times 3.14 \times 21 \times 21$

$18.84 \times 441$

$\Large{\pink{\bf{8308.44 {cm}^{2}}}}$

Done :)
