Answer:
Step-by-step explanation:
It makes 270 revolutions in one minute ie 60 seconds
Therefore, it makes 4.5 revolutions in a second.
In one revolution it covers a distance of 2π radians (one complete revolution)
So in half a revolution it covers π radians.
Hence, in 4.5 revolutions it turns through ( 4 x 2π + π )radians
ie 9π radians.
