1) The area of circle O is 81
.
2) The length of AB is 6.
This question deals with two different types of content
- probability and geometry. To answer it, we must figure out whether we
can determine a probability relationship, so let's start there.
- How is AC related to the rest of the diagram?
- What is the relationship between AC and the length
?
