please only do number 6, 7,8, and 19 SHOW ALL WORK(please write neatly. i can't read some tutors work) thank you

Find the ang 5. Number of revolutions = 525 t = 3.42 min 6. Number of revolutions = 7360 t = 37.0 s W= rpm 7. Number of revolutions = 4.00 W = rev/s t = 3.00 s 8. Number of revolutions = 325 rad/s t = 5.00 min W = W = 9. Number of revolutions = 6370 rpm 10. Number of revolutions = 6.25 t = 18.0 s t = 5.05 s W = rev/s W = rad/s 11. Convert 675 rad/s to rpm. 12. Convert 285 rpm to rad/s. 13. Convert 136 rpm to rad/s. 14. Convert 88.4 rad/s to rpm. 15. A motor turns at a rate of 11.0 rev/s. Find its angular speed in rpm. 16. A rotor turns at a rate of 180 rpm. Find its angular speed in rev/s. 17. A rotating wheel completes one revolution in 0.150 s. Find its angular speed (a) in rev/s. (b) in rpm. (c) in rad/s. 18. A rotor completes 50.0 revolutions in 3.25 s. Find its angular speed (a) in rev/s. (b) in rpm. (c) in rad/s. 19. A flywheel rotates at 1050 rpm. (a) How long (in s) does it take to complete one revolution? (b) How many revolutions does it complete in 5.00 s
