Rearrange formula to show a linear relationship between Frequency and Volume

[qq194]

please provide the f vs V data, and I will show you what I mean. Plus, I have already answered these questions in a previous post.

V= 0,000295m^3 f=172Hz
V= 0,000245m^3. f=188Hz
V=0,000195m^3 f=211Hz
V= 0,000145m^3 f=245Hz
V=0,000095m^3 f= 303 Hz
V=0,000045m^3 f= 440Hz

now it works, thank you , with me the graph looked like a straight line, only my associated function equation y=mx+b was not as perfect as yours. Many thanks, what program did you use?

thank you so much for your really great support!

"f" is frequency "V" is some kind of volume and $c_s$ is the speed of sound. By dimensional analysis, $A$ and $L$ are, respectively, some kind of area and length. I know all this because initially OP attached a pdf which was since deleted. There was no information on the physical situation in the pdf.

thanks for your help!

so that's the last question, how can I determine cs from this function equation between f and v now?because $$ y=kx^n $$
that describes only f and V in the diagram, can I determine cs with the help of these straight lines?

$$k=\frac{c_s}{2\pi}\sqrt{A/L}$$
