Question

Find area of a sector of a circle with radius 4 cm and sector angle is 120​

Answer 1

${\huge{\underbrace{\rm{Answer\checkmark}}}}$

$\longrightarrow \: \bf \: r \: = 4 \: cm \\ \bf \longrightarrow \: \theta \: = 120 \degree$

$\star \bf \: using \: the \: formula \: for \: area \: of \: sector$

$\mapsto \bf \: area \: of \: sector \: = \frac{ \theta}{360} \times \pi {r}^{2}$

$\bf\implies \: \frac{120}{360} \times 3.14 \times {4}^{2} {cm}^{2} \\ \\ \bf \implies \: \frac{1}{3} \times 3.14 \times 16 {cm}^{2}$

$\bf \implies16.74cm^{2}$
