Calculation for the Diameter of the Mash/Lauter tun

When we do dry milling for the grain, the usual height for the grain bed is 35cm.
Like the 7bbl mash/lauter tun, 240kg grain is OK to get 18 Plato wort.
After the mashing process, the final volume for the grain bed is about 0.432m3.
(Ps: here we have a usual formula for the final volume of the grain bed.
1000kg grain can finally get 1.8m3 grain bed, so 240kg is 0.432m3)
V(0.432m3)=S(πr2)*H(0.35m). Thus we can get the inner Diameter(2r)=1.260m.
Adding the 2x100mm insulation, the final outer Diameter is 1.460m.
Hope I have made myself clear. Also we can exchange ideas again in person.
