Answer:
It covers 110m on one revolution..
Therefore ,
2 π r =110
r=55÷ π
r=55×7/22
r=35/2
r=17.5m

Answer:
17.5 metres
Step-by-step explanation:
If the wheel covers 110 metres in one revolution it means perimeter of the wheel is 110 metres.
If r is the radius of the wheel, then
Circumference of the wheel = 2πr
Therefore 2πr = 110.
Or r = 110/2π = 110×7/(2×22) = 35/2 = 17.5.
Therefore radius of the wheel is 17.5 metres.
