SUMMARY
The angular speed of a high-speed sander with a disk radius of 4.00 cm, rotating at 1100 revolutions per minute, is calculated to be approximately 36.6 radians per second. This is derived by converting the revolutions per minute to radians per second using the formula: angular speed = (revolutions per minute) * (2π radians/revolution) / 60 seconds. The calculation shows that the disk completes over 36 full rotations every second, indicating a very high operational speed.
