Question

A wheel rotates 25,000 times to cover a distance of 88 km find its diameter

Answer 1

Answer:

3000.62 m

Step-by-step explanation:

25,000 divided by 88,000= 3000.62 m

Answer 2

Answer:

1.12m

Step-by-step explanation:

Distance covered = 88km or 88000m

Number of rotation = 25000

Distance covered in one rotation= 88000/25000=3.52 m

So, the Circumference of the wheel= 3.52 m

Circumference = pi x D

D = Circumference /pi

D= 3.52 /(22/7)

D= 1.12m
