Answer 1

Answer:

18.85 radians does it turn in 1 sec

Step-by-step explanation:

revolution= 180

time= 1 min= 60 sec

in 60 sec complete 180 revolution

in 1 sec complete 180/60 = 3 revolution

so in 1 sec complete 3 revolution

1 revolution= 2π radian

3 revolution= 3*2π radians

= 18.85 radians
