Find the area of the circle pictured. Use A = 3.14r2
http://curriculum.kcdistancelearning.com/courses/ALG1x-HS-A06/b/Exams/7Exam/7Exam_q24.gif
   A = 12.56n2 - 37.68n + 28.26 
   A = 12.56n2 + 28.26 
   A = 6.28n2 - 9.24

$$\textrm{Let}~ \pi = 3.14 \
\begin{align*}
    A&=\pi r^{\large2} \
    &=\pi(4n^{\large2}-12n + 9) \
    &=12.56n^{\large2}- 37.68n+28.26
\end{align*}$$
