Answer 1

Answer:

$1,947\ cm$

Step-by-step explanation:

The correct question is

A bicycle tire has a diameter of 62 cm. What is the distance the bicycle tire travels in 10 revolutions? Round your answer to the nearest centimeter

step 1

Find the circumference of the bicycle tire

we know that

The circumference of a circle is equal to

$C=\pi D$

where

D is the diameter

we have

$D=62\ cm$

substitute

$C=\pi (62)$

$C=62\pi\ cm$

step 2

What is the distance the bicycle tire travels in 10 revolutions?

we know that

One revolution subtends a distance equal to the circumference of the bicycle tire

so

Multiply the circumference by 10

$(10)62\pi=620\pi\ cm$

assume

$\pi =3.14$

$620(3.14)=1,947\ cm$
