A cone does not have any parallel lines
Infinitely many. There are infinitely many lines from the apex to the base. Every point on each of these lines is on the surface of the cone.
You can not use rubber fuel lines to replace the current brake lines due to the high operating pressure. You will need to replace them with brake lines, the rubber brake lines has a different construction to hold the pressure and not getting eaten away by the brake fluid, brake lines can hold over 2000psi when the pedal is heavily applied
Master cylinder brake lines are the most common brake lines on a the Chevy Malibu.
None. A right cone has no vertical lines. And what is a cone if it is not three dimensional?
If it is a right circular cone, it has an infinite number of planes of symmetry. If it is an oblique circular cone, it has one plane of symmetry.
You remove the wheels to replace brake lines.
The brake lines can be replaced by removing all of the retaining clips. The brake lines will need to be disconnected on both ends. Reverse the process to install the new brake lines.
Brake lines run from the master brake cylinder to each wheel, generally under the frame of the car.
Generally, none.
One, but it wraps all the way around the cone.
The axis of a right circular cone is perpendicular to every radius or diameter of the base.
