Answer:
radius r
distance =circumference =2πr covered of a circle
displacement = path between initial and final point
•°•2t will equal to diameter r+ r= 2r
Distance = 1round =2πr
2round =2x2πr=4πr
2&half round = 0.5x4πr
Displacement = 1round =0
2round =0
2&half round = diameter of a circle = r+r=2r
