Question

determine em radiano a medida dos arcos de 30 graus

Answer 1

regra de 3

π ⇒ 180°
x ⇒ 30°

$x= \frac{ \pi .30}{180} ~~~simplificando~~ \frac{~30:30}{180:30} = \frac{1}{6} \\ \\ x= \frac{ \pi }{6} \\ \\ 30^{\circ}\mapsto \frac{ \pi }{6} rad$

Answer 2

Boa tarde!

πrad → 180°

___________

Regra de três simples:

πrad----------180°

x-------------30°

180x=30

x=30/180 → 3/18 = 1πRad
