5000 revolutions=11000 m
1 revolution=11000/5000 m
circumference=11/5 m
2πr=11/5
πd=11/5
22/7×d=11/5
d=11×7/(5×22)
d=11×7/110
d=7/10 m
d=0.7 m
d=0.7×100 cm
d=70 cm

Step-by-step explanation:
5000 revolutions=11000 m
1 revolution=11000/5000 m
circumference=11/5 m
2πr=11/5
πd=11/5
22/7×d=11/5
d=11×7/(5×22)
d=11×7/110
d=7/10 m
d=0.7 m
d=0.7×100 cm
d=70 cm
hence, radius = 70/2=35
