Question

Transformar em radianos ou em graus
330 graus
225 graus
15 graus
7pi/6
7pi/4
4pi/3
5pi/9
2pi/3

Answer 1

Considerando a afirmação:

pi radianos = 180°


a) 330°

pi --- 180°
x --- 330°
180x = 330pi
x = 330pi/180
x = 33pi/18
x = 11pi/6 radianos



b) 225°

pi --- 180°
x --- 225°
x = 225pi/180
x = 15pi/12
x = 5pi/4 radianos



c) 15°

pi --- 180°
x --- 15°
x = 15pi/180
x = pi/12 radianos



d) 7pi/6

pi --- 180°
7pi/6 --- x
pi.x = 180.7pi/6
x = 30.7pi/pi
x = 210°



e) 7pi/4

pi --- 180°
7pi/4 --- x
x = 180.7/4
x = 45.7
x = 315°



f) 4pi/3

pi --- 180°
4pi/3 --- x
x = 180.4/3
x = 60.4
x = 240°



g) 5pi/9

pi --- 180°
5pi/9 --- x
x = 180.5/9
x = 20.5
x = 100°



h) 2pi/3

pi --- 180°
2pi/3 --- x
x = 180.2/3
x = 60.2
x = 120°
