Correct Answer - Option 1 : 1.1 km
Given:
Radius = 3.5 m
Number of revolution = 50
Formula used:
Circumference of circle = 2 π r
Number of revolution = Total distance covered/circumference of the wheel
Concept used:
The distance covered in one revolution is equal to the circumference of the circle
Calculation:
Circumference of circle = 2 π × 3.5
⇒ 2 × (22/7) × 3.5
⇒ 22 m
Now, Total distance covered in 50 revolutions = 50 × 22 = 1100 m = 1.1 km
∴ The distance covered by the circular wheel is 1.1 km
