Answer:
186 cm
Step-by-step explanation:
Since the bicycle wheel is making a rotation and not a revolution, the bicycle wheel is at one point.
The length of the trace of water left on the floor is simply the circumference of the bicycle wheel
Circumference = 2πR
where R = radius of the bicycle wheel
and π = pie
Circumference = 2 × (22/7) × 30 = 188.57143 cm
