Resposta:

a) 0,52333...

b) 0,785

c) 3,8777...

d) 5,669444...

e) 8,37333...

f) 21,63111...

Explicação passo-a-passo:

Fórmula:

graus/180 = ∝/ π

Pi aproximado a 3,14:

A)

30/180 = ∝/ π

30π = 180∝

∝ = 30π/180

∝ = 0,52333...

B)

45/180 = ∝/ π

45π = 180∝

∝ = 0,785

C)

220/180 = ∝/ π

220π = 180∝

∝ = 3,83777...

D)

325/180 = ∝/ π

325π = 180∝

∝ = 5,669444...

E)

480/180 = ∝/ π

480π = 180∝

∝ = 8,37333...

F)

480/180 = ∝/ π

480π = 180∝

∝ = 21,63111...
