Question

In making a 100000 revolution, a wheel covers 88km. the diameter of the wheel is

Answer 1

Hey mate !
______

The total distance travelled is 88 km = 88000 m

No. of revolutions = 1000

Now, Distance travelled in 1 revolution = 2 * 22/7 * R

Distance travelled in 1000 revolutions = 2 * 22/7 * R * 1000

=> 1000 * 2 * 22/7 * R = 88000

=> R = 14

Thus , radius of wheel = 14 m

and , diameter of wheel = 2 * R = 2 * 14 = 28 m
