In the space rectangular coordinate system, the graph of equation x & # 178; + Y & # 178; - 2Y = 0 is A sphere B cylinder C paraboloid D plane

In the space rectangular coordinate system, the graph of equation x & # 178; + Y & # 178; - 2Y = 0 is A sphere B cylinder C paraboloid D plane

The equation is reduced to x ^ 2 + (Y-1) ^ 2 = 1
It's a circle in a plane coordinate system
In addition, if the hidden condition Z is any real number, it is easy to get that the figure is a cylinder
