Question from the lawyer:  "Dr. Expert, I only see a 70° angle here, Exhibit A.  Kelly said that having this angle means you have a plane.  From what I see, none of the definition of a plane say that an angle defines a plane.  Explain how each definition proves that an angle defines a plane." 14. Definition 1: Three points that are not collinear.      
Proof:

15. Definition 2: A line and a point not lying on the line.
Proof:

16. Definition 3: Two lines which intersect     
Proof:

I need help with the proof :)

Abucket of paint has spilled on a tile floor. the paint flow can be expressed with the function p(t) = 6(t), where t represents time in minutes and p represents how far the paint is spreading. the flowing paint is creating a circular pattern on the tile. the area of the pattern can be expressed as a(p) = 3.14(p)^2 part a: find the area of the circle of spilled paint as a function of time, or a[p(t)]. show your work. part b: how large is the area of spilled paint after 8 minutes? you may use 3.14 to approximate pi in this problem.
