Solid of Revolution  Geogebra 5.0 3D - Cone

Solid of Revolution Geogebra 5.0  3D
A triangle in the xz-plane is revolved around the  z-axis producing a cone.
The triangles are generated using a sequence.

h = 4 (slider from 0 to 4, step 0.1)
r = 1.4 (slider from 0 to 4, step 0.1)
C: (0, 0, h)
A = Intersect(xAxis, yAxis)
Base = Circle(A, r)
θ_{MAX} = 0.5585053606381855 rad (slider from 0 to 6.283185307179586, step °)
Triangles = Sequence(Polygon[A, C, ((r * cos(θ)), (r * sin(θ)))], θ, 0°, θ_{MAX}, 5°)
