Question

a wheel rotates 25000 times to cover a distance of 88km find the radius

Answer 1

Answer:

0.56 m OR 56cm

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= 1.12

Radius = 1.12 /2

Radius = 0.56 m OR 56cm
