Two pulleys are connected by a belt. The larger pulley has a radius of 15 cm and the smaller pulley has a radius of 8 cm. The larger pulley rotates 25 times in 36 seconds. Find the angular velocity of each pulley in radians per second.

for the larger one i put 50π radians/36 seconds = 25π/18 radians per second

how do i calculate the angular velocity of the smaller pulley?
