Question

resolva a seguinte questão

Answer 1

α = 60⁰ = $\frac{1}{3} \pi$

$r = 8 \sqrt{3} . sen ( \frac{1}{3} \pi )$
$r =8 \sqrt{3} ( \frac{1}{2} \sqrt{3} )$
$r=12$

Area = $\frac{ \alpha }{2 \pi }$ amplo circulo

Area = $\frac{ \frac{1}{3} \pi }{2 \pi } \pi r^{2}$

$= \frac{1}{6} \pi r^{2}$

$= \frac{1}{6} \pi . 12^{2}$

$= \frac{144}{6} \pi$

$= 24 \pi$
