Lets work it out.
A(6) = 6 + (6-1)(-2)
6 + 5(-2)
6-10
-4
-4 would be your answer, unless it is A(n) = 6 + A(n-1)(-2)

$36 \pi$
The area of a circle is:
$A= \pi r^{2}$
Radius is equal to one half of the diameter
So the radius of the mirror is 6 inches
Now you can just plug this into the equation: 6 squared is 36, times pi
$A=36 \pi$ or if you multiply the pi in: 113.097 inches squared!
