Question

A wheel having radius one metre makes 30 Revolution per minute the linear speed of particle on the circumference will be ​

Answer 1

Answer:

44/7 meter

Explanation:

circumference of circle=2pai R

Answer 2

Answer: π

Explanation:

We have linear speed v= w*r

Where, w = 2πf and "f" is frequency

Given f= 30 rev per min

i.e. f= 30/60 = 0.5 rev per second

Now linear velocity is

V= w*r

= 2πf*r r= 1 m (given)

= 2 π * 0.5 * 1

= π m/s

Hope it helps...
