Arc Length & Sector Area
Webcomic #6 - "Noah's Arc" (11-18-11)
Since radian measure and degree measure of central angles are related, we can determine parts of a circle in different ways.
_______________________________________________

_______________________________________________
Sector Area Question:
A cow is tethered to a 100-foot rope, attached to the inside corner of an L-shaped building (as shown in the diagram).
Can you find the grazing area of the cow?
