Question

A wheel with radius 1 m rolled in a straight line through one complete revolution on a flat horizontal surface. How many metres did the centre of the wheel travel horizontally from its starting location?

Answer 1

2π

Explanation:

Sorry no time

Answer 2

6.28 m

Explanation:

Given: A wheel with radius
`1\text{m}` rolled in a straight line through one complete revolution on a flat horizontal surface.

To Find: How many meters did the center of the wheel travel horizontally from its starting location.

Solution:

consider the figure attached.

radius of wheel
`=1\text{m}`

horizontal distance traveled by wheel in one complete revolution

`=\text{circumference of wheel}`

`=2\pi\text{r}`

`=2*3.14*1`

`=6.28\text{m}`

As, the distance traveled by center is equal to the distance traveled by wheel

`6.28\text{m}` is traveled by the center
