Thread: Help with Circles and Revolutions

There are 1760 yards in a mile. A certain wheel makes 17,600 revolutions in 40 miles. What is the number of yards in the radius of the wheel? Give your answer as a decimal to the nearest tenth of a mile.

the wheel travels a distance of in one revolution, so that would mean the wheel's circumference is 4 yds, correct?

Oh, thank you so much!

So you got the radius from that?

Well if the circumference is 4 yards, then you can divide it by 2 to get the radius.
