Two wheel gears are connected by a chain. The larger gear has a radius of 8 centimeters and the smaller gear has a radius of 3 centimeters. The smaller gear completes 24 revolutions in 20 seconds.

 

What is the linear velocity of each of the gears in centimeters per minute?

 These below are my awnsers choices

  • The linear velocity of the gears is the same. The linear velocity is 432π centimeters per minute.

  • The linear velocity of the smaller gear is 144π centimeters per minute. The linear velocity of the larger gear is 54π centimeters per minute.

  • The linear velocity of the gears is the same. The linear velocity is 7.2π centimeters per minute.

  • The linear velocity of the smaller gear is 432π centimeters per minute. The linear velocity of the larger gear is 144π centimeters per minute.

The smaller  gear  completes  72 revs per minute

This  is     72 * 2pi * 3  =  432pi  cm / min

 

They both will have the same linear velocity   

They will have different angular velocities
