find the angle between the hour hand and minute hand in circular measure at 4 O
At 4 O clock, the minute hand is on the 12 and hour hand is on the 4.
Now the angle formed is 4/12 of the total number of the degree in the circle which is 360 degree.
So (4/12) * 360
= 4*30
= 120 degree
So angle formed at 4 O clock is 120 degree.
