Question

An automobile is pushed so that its wheels turn one​-half of a revolution. If the tires have a radius of 17 ​inches, how many inches does the car​ move?

Answer 1

The car moves approximately 53.38 inches.

Explanation:

We are given the following in the question:

Radius of tire = 17 inches

The wheels of an automobile turn one​-half of a revolution.

One revolution is of
`2\pi`.

one​-half of a revolution is will be of:

`(1)/(2)* 2\pi = \pi`

Relation between arc length, angle measure and radius is:

`s = r\theta = 17\pi = 53.38`

Thus, the car moves approximately 53.38 inches.
