how is it calculated?*

- math -
**Reiny**, Monday, April 7, 2014 at 2:57pm1 rotation = 360° = 2π radians

at 7:00 the minute hand is on the 12 (straight up) and the hour hand has moved 7/12 of a rotation

(7/12)(2π)

= 7π/6 radians ---> or 210°

so the smaller angle between the two hands

= 2π - 7π/6

= 5π/6 radians ------> 150°
