Math Problem Statement
A crossed belt connects a 24-centimeter pulley (x = 12-cm radius) on an electric motor with a 48-centimeter pulley (y = 24-cm radius) on a saw arbor, as shown in the figure below. The electric motor runs at 1,900 revolutions per minute.
Let L be the total length of the belt. Write L as a function of π, where π is measured in radians.
