Question

"A wheel is rolling without slipping on a flat surface". If the diameter of the wheel is 1 meter, how far does the hub of the wheel move when the wheel turns once?

Answer 1

6.28 m

Step-by-step explanation:

The hub or centre of wheel will move a distance equal to the circumference

of the wheel .

Circumference of the wheel

= 2π R

R radius of the wheel is given as 1 m

So circumference

= 2 X 3.14 X 1 = 6.28 m

Hub will cover a distance of 6.28 m
