Question

The diameter of a truck tire is 22inches Approximately how fat will the truck have traveled after 5 rotations of these tires

Answer 1

The truck have travelled 345.5 inches after 5 rotations of the tires

Explanation:

Given:

Diameter of the tyre= 22 inches

Number of rotations= 5

To find:

Distance travelled after 5 rotations=?

Solution:

We have given with diameter,

So let radius be r

r=
`(diameter)/(2)`

`r=(22)/(2)`

r=11 inches

The distance covered by one rotation is given by circumference

Circumference =
`2\pi r`

Substituting the values, we get

Circumference =
`2*\pi* r`

Circumference =
`2*\pi* 11`

Circumference =
`2*\3.14* 11`

Circumference =
`6.28* 11`

Circumference = 69.11

Now for 5 rotation,

Distance travelled =
`5*(\text{circumference value})`

Distance travelled =
`5*(69.11)`

Distance travelled =
`5*(69.11)`

The truck will travel 345.5 inches.
