A space station consists of two donut-shaped living chambers, A and B, that have the radii shown in the figure. As the station rotates, an astronaut in chamber A is moved 369 m along a circular arc. How far along a circular arc is an astronaut in chami moved during the same time if r_a = 266 m and r_b = 165 m? Note: Express your answer in whole numbers. No unit is re for the final answer. Set your calculator in radians.
