Answer 1

Answer:

!!!!!!!!! ........................ ..........

Answer 2

Answer:

0.25 seconds

Step-by-step explanation:

Given,

Wheel rotates 35 times in one seconds,

That is,

1 second = 35 rotation,

⇒ Time taken in one rotation = $\frac{1}{35}$ second,

Now,

One rotation = $2\pi$ Radian,

⇒ Time taken in $2\pi$ radians = $\frac{1}{35}$ second,

⇒ Time taken in 1 radians = $\frac{1}{70\pi}$ second,

⇒ Time taken in 55 radians = $\frac{55}{70\pi}$ second ≈ 0.25 seconds
