can you tell me how to actually do this.
find thenumebr of radians through which the hour hand of a clock turns in 5 hours.
i don't know what i did, this is what i wrote:
360degrees=1 hour
1800 degrees=5 hours
1800(pi/180)
somehow i got 10pi which is apparantly wrong.

you are making it harder than it has to be
once around is 2pi radians
5 hours is 5/12 of "once around"
so radians in 5 hours = 5/12(2pi) = (5/6)pi radians
