Circumference + perimeter =38
x = circumference of circle
find r in terms of x
2\pir=x
r=\frac{x}{2 \pi }
Area=\pir^2
so..
A=\pi(\frac{x}{2 \pi })^2
=\pi(\frac{x^{2} }{4 \pi ^{2} })
=\frac{x^{2} }{4 \pi }

(38-x) is perimeter
then 
\frac{38-x}{4}
(\frac{38-x}{4})^2
\frac{x^{2} }{4 \pi } + (\frac{38-x}{4})^2
then you graph it and it equals
16.716 cm the circumference of the circle
