Answer:
an apparent solution that does not satisfy the original equation
Step-by-step explanation:
Usually, an extraneous solution is introduced by the solution process. Sometimes it takes the form of multiplying an equation by 0, often the result of eliminating the denominators of rational functions.
Other times, it takes the form of adding branches to a function that are unintended or undefined. (Squaring a square root will often introduce "solutions" that require the square root to be a negative value.) The attached graph shows that x=4 is an extraneous solution to ...
√x = x-6
It shows up when the equation is squared:
x = x² -12x +36 ⇒ (x -9)(x -4) = 0
The "solution" x=4 is extraneous because it does not satisfy the original equation.
As in this graphed example, using graphical methods to find solutions can often avoid extraneous solutions.

Answer:
113.04
Step-by-step explanation:
I flipen love this but anyways so a=start with your formula which would be
A=
so then you just subsitute which then would be
3.14*6*6
and you get
113.04
anyways i hope that helps and have a great day :)
