plz solve it fast​

Answer 1

Step-by-step explanation:

let r be the radius of the wheel

distance covered in 1 revolution= 2πr

distance covered in 5000 revolution= 5000×2πr

according to given information we have,

5000×2πr =. 11km

5000×2×22/7×r=11×1000

= 70cm

hence diameter of the wheel is 70cm or 7/10 m
