Answer:
simple
Step-by-step explanation:
The radius of the wheel can be solved from its given speed and RPM.
Converting km/h to m/min
speed = 66 km / h = 66000 m / 60 min
speed = 1100 m / min
Converting one revolution to meters
1100 m / min = 500 revolution / min ... (given)
500 revolutions = 1100 m
1 revolution = 2.2 m
Solving for the radius of the wheels in meters
1 revolution = 2.2 m
2 * pi * radius = 2.2 m
radius = 2.2 m / 2 * pi
radius = 1.1 m / pi
radius = 0.3501 m
