Question

12. Area of minor sector of circle having centre 0 is 150 and radius is 5 then find length of arc is
(* = 3.14)​

Answer 1

$Given \: Minor \:sector \:of \:circle \: having \\centre \: O.$

$Radius (r) = 5 \:units$

$Angle \: of \: the \: sector (x) = 150\degree$

$\boxed { \pink { Area \:of \:the \:sector (A) = \frac{x}{360} \times \pi r^{2} }}$

$A = \frac{150}{360} \times 3.14 \times 5^{2}$

$A = 32.71 \:square \: units$

Therefore.,

$\red {Area \:of \:the \:sector (A)} \green {= 32.71 \:square \: units}$
