Answer 2

Heya,

Given:-
Distance=11km=11,000m
Revolution=5,000

Circumference of the wheel= distance/revolution
=> Circumference of the wheel= 11,000/5,000
=> Circumference of the wheel= 11/5
=> Circumference of the wheel= 2.2m

To find diameter of the wheel,

Circumference= πd

=> 2.2 = 22/7×d
=> 2.2×7/22 = d
=> 15.4/22 = d
=> 15.4/22×10/10 = d
=> 154/220 = d
=> 0.7 = d

Therefore,

The diameter of the wheel is 0.7m

Hope my answer helps you :)
