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 1 meter, and it made 8000 rotations during the trip.

How far did the bus travel?
Give your answer in terms of pi.

Answer 1

Think Winnie.

The distance a wheel traveled can be determined by using the circumference.  The circumference of the wheel is pi meters. (formula is pi * diameter)

So if there were 8000 rotations, then the bus traveled 8000pi meters.
