please send me the answer with solution​

Answer 1

Answer:

pi radian = 180 degrees .

so 360 degrees = 2 pi radian

In the question it is given that in 1 minute , it makes 180 revolutions.

Now you must be knowing that 1 revolution = 360 degrees = 2 pi radians .

so it makes 2 X 180 pi radians = 360 pi radians in 1 minute .

Now you know that 1 minute = 60 seconds.

so in 60 seconds , it makes 360 pi radians

   in  1 second , it makes 360 pi / 60 radians = 6 pi  radians
