RRB Group-D Model Paper 17 with answers for online practice

Given:
Distance = 44 km
Revolutions = 5000
Formula used :
Perimeter of circle = 2πr
Where, r is the radius of the circle.
Calculations:
A wheel travels a distance of 44 km in 5000 revolutions.
∴ 5000 × 2π × r = 44
⇒ 5000 × 2 × (22/7) × r = 44
⇒ r = 7/5000 km
⇒ r = 7/5 m
⇒ r = 1.4 m
Note :
1 Km = 1000m
