Question

I need help with the problem and writing in terms of function notation

Answer 1

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

$\begin{gathered} Circumference\text{ = 136 =2}\times\pi\times r\text{ } \\ \Rightarrow r=\frac{136}{2\pi} \\ Area\text{ = }\pi\times r^2 \\ \Rightarrow\pi(\frac{136}{2\pi})^2 \end{gathered}$

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

$\begin{gathered} \text{Area = 5.37 = }\pi\times r^2 \\ \Rightarrow r=\sqrt[]{\frac{5.37}{\pi}} \\ \text{circumference = 2}\times\pi\times r \\ \Rightarrow\text{ 2}\pi\sqrt[]{\frac{5.37}{\pi}} \end{gathered}$
