Answer:

484 Inch

Explanation:

Radius of the tire=11 inch

The distance which the tire covers in 1 revolution is the circumference of the tire.

Circumference of a circle=2πr

Therefore:

Distance of the tire in 1 revolution=2*π*11=22π inches

From the above, we can then determine the distance which the tire travels in 7 revolutions.

Distance if the tire in 7 revolutions=7*22π

=483.81 Inch

≈484 Inch ( to the nearest inch)

The tire travels approximately 484 Inch in 7 revolutions.
