No, the maximum energy is emitted in the direction of motion of a charge. No energy is emitted in the perpendicular direction. The profile of the drop between these two angles is determined by the velocity (especially whether relativistic or not).
Yes, synchrotron radiation is emitted perpendicular to the circular path of the electrons. This is because the radiation is generated when the electrons are deflected, or accelerated, due to the magnetic field in the synchrotron. The emitted radiation is tangential to the circular path, resulting in a perpendicular radiation pattern.
In a right circular cone a line from the vertex to the center of the circular base is perpendicular to the base. In an oblique circular cone that same line will not be perpendicular.

The axis of a right circular cone is perpendicular to every radius or diameter of the base.

Strictly, if it has a circular base, it is a circular cylinder. Otherwise, it could have an oval base. If the long axis is at right angles (perpendicular) to the plane of the base, then it is a right circular cylinder.
In michelson interferometer the mirros are perpendicular and because of our eye viewed direction and angle theta the fringes are circular
A Right Circular Cone is one wherein the base of the cone is circular and the axis of the cone is perpendicular to the base and passes through the center of the base and the vertex of the cone.
If a right circular cone intersects a plane that runs perpendicular to the cone's axis but does not pass through its vertex the resulting curve will be a circle.
