★ Given :-

Radius of circle is 21 cm.

Angle of sector is 60°

★ To Find :-

Area of sector

★ Solution :-

We know that

$\LARGE{\boxed{\blue{Area \: of \: sector = \frac{\theta}{360} \pi r^{2}}}}$

_______________[Put Values]

${ \sf{ → Area \: of \: sector = \frac{{ \cancel60}}{{ \cancel360}} \times \frac{22}{7} \times 21 \times 21 }} \\ \\ { \sf{→ Area \: of \: sector = \frac{1}{6} \times \frac{22}{{\cancel7}} \times{\cancel 21}\times 21}} \\ \\→ { \sf{Area \: of \: sector = \frac{11}{{\cancel3}} \times{\cancel3}\times 21 }} \\ \\ {\sf{11\times21}}{ \sf{→ Area \: of \: sector = \:231 \: cm^{2} }}$
