You are going on a field trip in a school bus. A special detector placed on one of the bus's tires counts the number of rotations completed by the tire during the journey. The tire's diameter is 1 meter, and it made 8000 rotations during the trip.
How far did the bus travel?
Give your answer in terms of pi.

According to question,
Perimeter of Tyre × No of Revolutions = Distance Travelled
Now,
Perimeter of Tyre = 2πr
= 2π(1/2) (d = 2r ; r = d/2 ; r = 1/2)
= π m.
Then, Substituting these in the Formula:
Distance travelled = π × 8000
= 8000π m
Hence Distance travelled by the bus = 8000π m.
