Answer 1

The distance bicycle tire travels is 1946.8 cm.

Explanation:

Given:

Diameter of bicycle tire = 62 cm.

The bicycle tire travels in 10 revolutions.

Now, to find the distance the bicycle tire travels in 10 revolutions.

Diameter = 62 cm.

Radius (r) =
`(Diameter)/(2)=(62)/(2)=31\ cm.`

So, we get the circumference first by putting formula:

`Circumference =2\pi r`

`Circumference =2* 3.14* 31\\\\Circumference =194.68\ cm.`

Thus, we get the circumference of tire 194.68 cm.

Number of revolutions the tire travels = 10.

Now, to get the distance the bicycle tire travels we multiply circumference of tire by number of revolutions the tire travels:

`194.68\ cm* 10\\\\=1946.8\ cm.`

Therefore, the distance bicycle tire travels is 1946.8 cm.
