Question

transforme as medidas em radianos π .

a)230°
b)715°
c)900°
d)90°
e)300°

Answer 1

a)

230/x=180/1π
180x=230π
x=230π/180
x=(23/18)π

$\frac{23}{18} \pi$

b)

715/x=180/π
180x=715π
x=(715/180)π
x=(143/36)π

$\frac{143}{36} \pi$

c)

180x=900π
x=(900/180)π
x=5π

$5\pi$

d)

90/x=180/π
180x=90π
x=(90/180)π
x=(1/2)π
x=π/2

$\frac{\pi}{2}$

e)

300/x=180/π
180x=300π
x=(300/180)π
x=(30/18)π
x=(10/6)π

$\frac{10}{6} \pi$
