Question

The tire's diameter is 1 meter, and it made 8000 rotations during the trip. How far did the bus travel?

Answer 1

The circumference of the tire = pi x diameter = 3.14 x 1 = 3.14 meters

every rotation the tire travels 3.14 meters

3.14 x 8000 = 25120 meters

1 kilometer = 1000 meters

25,120 meters /100 = 25.12 kilometers

answer: 25.12 kilometers
