# ContourPlot3D in cylindrical coordinates [closed]

My function x=x(k,phi) is defined implicetly: h3(x,k,phi)==0. Function h3 is defined through NSolve, so I cannot really express x through k and phi. I need to Plot this function in 3D:

But, I need to plot in cylindrical coordinates, so that phi is polar angle, k is radius.

Similar questions:

Here explicit function was used. I need to plot implicit.

Here ParametricPlot3D was used. But again, function was explicit.

Thanks, Mikhail

• It should not be too hard to make the replacements Sqrt[x^2 + y^2] and ArcTan[x, y] in the right places, no? – J. M.'s technical difficulties Oct 30 '15 at 23:52
• Oh, yes, that actually works! – Mikhail Genkin Oct 31 '15 at 0:07
