The Essential Volume Equation

So I was wanting the measure the volume of my unit but I couldn’t find an equation that used cirumference to do it so I decided to make one since I found it such a pain to convert my girth to a radius.

area of a circle= A = πr^2
circumference= C = 2πr
so I solved that r= C/2π
thus when plug A=π(C/2π)^2 and simplify you get Area= (C^2)/4π
multiply this by length and you get volume. So,

Volume= [(C^2)/4π] x L

where C is your girth. Maybe someone will find this helpful to calculate volumes more easily.

Sorry the Pi symbol looks funny. π is Pi. Pi = 3.14 for our purposes here BTW. And I know I have seen some similar equations on another threadm, but search failed me one so I posted it.

easiest is length x girth x girth x .08

Why would you want to calculate the volume?? Why would you not use displacement? Fill a deep cup with water, measure the volume, stick your dick in the cup, measure the new volume, subtract the difference. Why use a complicated formula? I apologize if I am overlooking something.

I like my formula because it is easy to see percentage gain, without a cup of water. I can find within a few seconds that I have 20% more dick now than I used to, for example.
