Okay so the circle on the line plot, if it is empty In the middle it is > or < if it is solid it is ≤ ≥. In this case it not solid so it will be > or < . The plot is at -1 1/2 and is going positive. So it would be a > -1 1/2
V ,= 4/3 πr³
solve for r
3V/4=r³
so r is the cubed root of 3V/4

Hope it helps ^^
