I know the height of my tent is (104/55) which is 1.89m, and the safety capacity is 20.8 m^3. However, in my volume equation I have an unknown variable 'r". How do I calculate this? V = (-√3 h^3+3√3 r^2 h)/(2) Any help would be appreciated thanks, MathsKid007

That is, r is the radius of the tent. Since this is a hemi-spherical tent, that is the same as the height of the tent, 1.89 m.
