Question

find area of sector, radius=8cm arc length=3cm​

Answer 1

$\huge { \mathfrak{\boxed{ \pink{A}}}{ \boxed{ \green{n}}{ \boxed{ \red{s}}{ \boxed{ \orange{w}}{ \boxed{ \blue{e}}{ \boxed{ \orange{r}}}}}}}}$

Given:-

Radius of the circle,r=8cm

Arc length=3cm

${ \Large{ \sf \: area \: of \: sector \: of \: circle, A= \frac{1}{2} lr}}$

$\Large \sf= \frac{1}{ \cancel2} \times \cancel8 {}^{4} \times 3$

$\Large \sf \: A \: of \: sector = 12 {cm}^{2}$
