As you can a see, as the wheel turns the distance traveled along the ground in one turn is equal to the circumference. So what distance would be traveled by a thousand rotations? That's what the question is asking.

The diameter of the front wheel of Michael's bicycle is 668 mm.
A) work out the circumference of the wheel.
Give your answer in centimetres
(answer: 209.8 cm)
b) Micheal rides his bicycle
work out the distance cycled when the wheel makes 1000 complete turns.
Give your answer in km
I don't understand b
What am I supposed to do?
Circumference of a circle is pi* the diameter and for 1000 turns it would be 1000*Pi*the diameter,to get the distance because after a full turn the tyre has moved along the whole circle once.Remember to convert the mm into cm.
