Round your answer to the nearest mm.

HURRY PLEASE!!!

Answer 1

3770

Explanation:

Answer 2

3770 mm.

Explanation:

The diameter of of the wheels is 60mm, that means the radius is 30mm.

Now for one revolution of the wheels, they cover the distance of
`2\pi *30mm=188.5mm.` on the ground.

For 20 revolutions, the distance covered will be 20 times this.

Thus

`Distance\: covered =188.5*20=\boxed{3770mm}`

Which is our answer.
