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

Answer:

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

Step-by-step 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= $\frac{diameter}{2}$

$r=\frac{22}{2}$

r=11 inches

The distance covered by one rotation is given by circumference

Circumference =$2\pi r$

Substituting the values, we get

Circumference =$2\times\pi\times r$

Circumference =$2\times\pi\times 11$

Circumference =$2\times\3.14\times 11$

Circumference =$6.28\times 11$

Circumference = 69.11

Now for 5 rotation,

Distance travelled = $5\times(\text{circumference value})$

Distance travelled = $5\times(69.11)$

Distance travelled = $5\times(69.11)$

The truck will travel 345.5 inches.
