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.
