Question

A bicycle tire has a diameter of 66 centimeters. How many times must the tire rotate to

Travel one kilometer?

Answer 1

Answer: about 482 times

Step-by-step explanation: The circumference is the distance the bicycle will travel in one rotation.

The distance the bicycle must travel is 1km = 1 000m = 100 000cm so we can represent the rotations with 100 000/66pi which when evaluated with a calculator gives about 482.2877.

Therefore the wheel must rotate about 482 times to travel 1 km
