Suppose C, R, A, and S are functions such that:

A) Function notation to represent the area of a circle whose circumference is 136 cm.

Thus, the function notation is


\begin{gathered} Circumference\text{ = 136 =2}*\pi* r\text{ } \\ \Rightarrow r=(136)/(2\pi) \\ Area\text{ = }\pi* r^2 \\ \Rightarrow\pi((136)/(2\pi))^2 \end{gathered}

B) Function notation to represent the circumference of a circle whose area is 5.37 cm².


\begin{gathered} \text{Area = 5.37 = }\pi* r^2 \\ \Rightarrow r=\sqrt[]{(5.37)/(\pi)} \\ \text{circumference = 2}*\pi* r \\ \Rightarrow\text{ 2}\pi\sqrt[]{(5.37)/(\pi)} \end{gathered}
