Help with this maths question?
I don’t want the answer, I would just like to know how I go about working this out as I have forgotten:
Billy likes to go cycling, his bike wheels have a diameter of 90cm.
Billy counts the number of revelations the wheel makes. It makes 140 revolutions, how far has Billy cycled? Give your answer to the nearest metre.
