Question

expresse radiano de 30 graus ?

Answer 1

regra de tres.
$\frac{30}{180} = \frac{x}{ \pi }$
$180x=30 \pi$
$x= \frac{30 \pi }{180}$
$x= \frac{15 \pi }{90}$
$x= \frac{5 \pi }{30}$
$x= \frac{1 \pi }{6}$

então o radiano de 30 graus é $\frac{1 \pi }{6}$

Answer 2

Boa tarde!

πrad → 180°

___________

Regra de três simples:

πrad----------180°

x-------------30°

180x=30

x=30/180 → 3/18 = 1πRad
