I hope we can use the formula V=2pi%5E2%2Ar%5E2%2AR where R is the distance from the center of the torus to the axis of rotation, and r is the radius of a cross section circle (cutting along the axis).
In that case,
%2840000pi%5E2%29mm%5E3=2pi%5E2%2820mm%29%5E2R --> 40000mm%5E3=2%2A400mm%5E2%2AR --> R=40000mm%5E3%2F%282%2A400mm%5E2%29 --> highlight%28R=50mm%29
