4. It moves 756,000° in one half hour.
If a pulley rotates 70 times a minute, how many degrees is that a second?
How many degrees will the pulley from #5 rotate in ½ hour?
It moves 420° in one second.
It moves 756,000° in one half hour.

5. If a circle whose radius is 5” has an angle of 3
If a circle whose radius is 5” has an angle of 3.8, what is the arc length?
If a circle whose radius is 24m has an angle of 78°, what is the arc length?
What would the sector area be with the information from #8?
s = rӨ
The arc length is 19”.
s = rӨ
The arc length is 32.7 m.
The sector area is m2.
