in one rotation it will cover 2200/200
=11m
so in 11m wheel will rotate one time I.e it's circumference = 2πr
11=2×(22/7)×r
11×7=44r
r=(11×7)/44m
r=7/4m
r=1.75m
=11m

11×7=44r
r=(11×7)/44m

Radius of the roller :- 1.75
explanation:
Roller make 200 rotation to cover a distance = 2200m
2×22/7×r ×200 = 2200
r = 2200×1/2×7/22×1/200
r= 1100×1/200×7/22
r= 11/2×7/22
r= 7/4 = 1.75
explanation:
Roller make 200 rotation to cover a distance = 2200m
2×22/7×r ×200 = 2200
r = 2200×1/2×7/22×1/200
r= 1100×1/200×7/22
r= 11/2×7/22
r= 7/4 = 1.75
