Step-by-step explanation:
Find the radius r by finding the distance between (12,-1) and (0,-1) using the distance formula.

The radius is 12.
So the circumference of the circle is 
So the area of the circle is 
5X^2 - 45
5(X^2 - 9)
5(X - 3)(X + 3)
4X^2 - 324
4(X^2 - 81)
4(X - 9)(X + 9)
Answer:
1,056 gifts
Step-by-step explanation:
If twelve relatives give gifts to one another
This means each of the twelve relatives gets gifts from the other 11 relatives
=12 relatives * 11 gifts
