Question

Determine a medida, em radiano , equivalente a :
30 graus
120 graus
225 graus
300 graus
240 graus

Answer 1

Resolveremos por regra de 3.

Sabemos que 180°= π rad

Logo:

a) 180°_____π

30°_____ a

a= 30π/180

a= π/6 rad

b) 180_____π

120_____ b

b=120π/180

b= 2π/3

c) 180_____π

225____c

c= 225π/180

c= 5π/4

d) 180_____π

300____d

d= 300π/180

d=5π/3

e) 180___π

240___e

e= 240π/180

e= 4π/3
