Question

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 111 meter, and it made 800080008000 rotations during the trip.
How far did the bus travel?

Answer 1

First you need to find the circumference of the circle because 1 revolution is 1 length of the circumference. The formula for the circumference is C=2πr or C=πd, if the diameter is 1 meter then the circumference is π1 which is just π, and if it travelled 8000 rotations then that would mean it travelled 8000π, so it travelled 8000π in meters
