A sport utility vehicle has tires which are 110cm in diameter If the wheel is rotated through 30 revolutions,how far forward does a point on the tire travel?

Answer 1

The circumference of the tire can be calculated as:

C = πd
C = π(110cm)
C ≈ 345.4cm

So for one revolution of the tire, a point on the tire travels 345.4cm forward.

Therefore, for 30 revolutions, a point on the tire travels:

30 revolutions x 345.4cm/revolution = 10,361.2cm or 103.612m (rounded to three decimal places)

So a point on the tire travels approximately 103.612 meters forward after 30 revolutions of the wheel.
