A bicycle tire has a diameter of 62 \text{ cm}62 cm62, start text, space, c, m, end text. What is the distance the bicycle tire
navik [9.2K]

Answer:

The distance bicycle tire travels is <u>1946.8 cm</u>.

Step-by-step 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) = \frac{Diameter}{2}=\frac{62}{2}=31\ cm.

So, we get the circumference first by putting formula:

Circumference =2\pi r

Circumference =2\times 3.14\times 31\\\\Circumference =194.68\ cm.

Thus, we get the <u><em>circumference of tire 194.68 cm.</em></u>

<u><em>Number of revolutions the tire travels = 10.</em></u>

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

194.68\ cm\times 10\\\\=1946.8\ cm.

Therefore, the distance bicycle tire travels is 1946.8 cm.
