Riemann's Sum Problem

Brief Overview
What I've done so far:

The Question
If the safety capacity for the benign use of a camping gas lamp inside a confined space is (104÷5) m^3, calculate whether it would be safe to use the lamp within the lightweight ‘pop-up’ tent.
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,

If I am reading this correctly, r is the radius of the hemi-spherical struts supporting the tent. 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.
