: Question:
The minute hand on a clock is 6" long, how far does it move in 25 minutes?
The answer I show in the solutions manuel shows
150degrees = 5pie over 6, divide by 6 = 5pie = 15.71 inches
How did they get 5pie over 6 from 150degrees?

You can put this solution on YOUR website!
25 minutes is (25/60)ths of a complete circle.

and a circle is 360 degrees... or 2%2Api radians. THIS IS ALL YOU SHOULD REMEMBER! Forget any formula that a book gives you.

So...
(25/60) of 360 is 150 degrees and in radians
(25/60) of 2%2Api is %285%2Api%29%2F6+ radians

is that any clearer?
