Transforme em π rad :<br>a)30°<br>b)40°<br>c)45°<br>d) 50°
Roman55 [17]

Answers:

a) \frac{1}{6} \pi rad

b) \frac{2}{9} \pi rad

c) \frac{1}{4} \pi rad

d) \frac{5}{18} \pi rad

Step-by-step explanation:

In this case we are dealing with angles, which can be expressed in degrees (\°) or radians (rad).

Now, before making the conversions we have to know the equivalence between degrees and radians:

180 \°=1 \pi rad

Taking this information into account, let's begin with the answers:

a) 30\° \frac{1 \pi rad}{180 \°}=\frac{1}{6} \pi rad

b) 40\° \frac{1 \pi rad}{180 \°}=\frac{2}{9} \pi rad

c) 40\° \frac{1 \pi rad}{180 \°}=\frac{1}{4} \pi rad

d) 50\° \frac{1 \pi rad}{180 \°}=\frac{5}{18} \pi rad
