Question

Hello I was wondering if I got this answer right and correct. The circular blade on a saw has a diameter of 5.5 inches and rotates at 3200 revolutions per minute.
A) Find the angular speed in radians per second.
1A) 335.103 rd/s
B) Find the linear speed of the saw teeth as they contact the wood being cut in ft/sec.
1B) 921.533 ft/s

Answer 1

Your first answer is correct.
The second answer is incorrect because you need to be careful with units.
The diameter is given in inches. From that, you must calculate the radius.
The answer must be in ft/s, so you need to convert inches to feet.

Answer 2

well I did put it in ft/s

Answer 3
