Respuesta :

As we know that

[tex]1 revolution = 2\pi radian[/tex]

now we know that

[tex]3.5 revolution = 3.5 rev\times \frac{2\pi rad}{1 rev}[/tex]

[tex]3.5 rev = 21.98 rad[/tex]

so it is 21.98 radian

Answer:

The right answer is 21.98 rad

Explanation:

You can see that  

2 π radians becomes one revolution when you use the arc length formula:

s=rθ

Let  

θ =2π . That means:

s =C=2πr

By putting the values and solving we get 21.98 radians
