Awheel on ryan's bicycle is 2.2ft in diameter. ryan races the bicycle for 248ft. how many times does the wheel turn as the bicycle travels this distance? use the value 3.14

So if Ryan's wheel is 2.2ft in diameter, that simply means, the radius is half that, or 1.1ft, how much terrain does it cover in one-go-round? or a cycle/revolution

well, it covers the arc of the circumference, now, the circumference of a circle is C=2πr  <-- r = radius, now, r = 1.1 then C=2π*1.1

how many go-round are there then in 248ft?  well 

16 minutes is correct
