Question

Determine the number of Radians between the hour hand and the minute hand of a clock at exactly 7:00

Answer 1

Draw it out and I'll help.

Answer 2

I keep getting 120 degrees but idon't know how to get it in radians.

Answer 3

Ahh, well remember that 360 degrees=2pi radians.

A fancy way to look at this is:

180 deg= pi rad

so...

(pi rad)/(180 deg)=1

and since you can multiply anything by 1 without changing anything,

(120 deg) * (pi rad)/(180 deg) = answer in radians.

This works because it divides out the degrees units since deg/deg=1 leaving radians behind.
