Proof by contradiction is a form of proof that establishes the truth or the validity of a proposition, by showing that assuming the proposition to be false leads to a contradiction. I googled this so it may not be correct
Well, you have to simplify the bottom part to be able to answer it as a whole number. Hope this helps.
Presumably we're being asked for the line which passes through (3,5) and (-1,5) which is simply
Formula: A = pi(r)^2
1/4(2)^2pi
1/4 * 4 pi = just pi
The area would be 3.14
