Question from Jules, a student: How far does a wheel of radius 2 feet roll along level ground in making 300 revolutions? |
Jules,
The circumference of a circle of radius r feet is 2 π r feet.
What is the circumference of your wheel? That's how far it goes in one revolution. How far does it go in 300 revolutions?
