The apex angle of the cone is the angle that the apex takes. This is measured by the two intersections the cone takes through a perpendicular plane defined by the apex and the center of the circular base.

If a right circular cone is intersected by a plane so that the intersection goes through the cone's vertex as well as an edge of each nappe what shape is produced?

If a right circular cone is intersected by a plane so that the intersection goes through the cone's vertex as well as an edge of each nappe, the shape produced is a line. Not asked, but... If the angle of the plane is less than the angle of the cone, then the intersection is a point. If the angle of the plane is greater than the angle of the cone, then the intersection is two lines intersecting at the vertex. If the plane insersects at other than the vertex, then the intersection is a circle when the plane is perpendicular to the cone's axis, an ellipse when the plane's angle is less than the cone's angle, a parabola when the planes's angle equals the cone's angle, and two hyperbole's in the last case.


How many corners and faces are on a cone?

there are 2 Faces on a cone, there is a technically immeasurable amount of corners, because the ca just keep cutting the angle finer and finer on the circular end and making more corners. though you'll get your bottom whipped if you say this to your teacher, the amount of vertexes on a cone is: 1+(∞)


What is produced when you slice a cone with a that is parallel to the base of the cone?

The interception of a plane with a cone parallel to the base of the cone is a circle.

What is apical angle in cone?

The apical angle of a cone is the angle formed at the apex (or tip) between the two sloping sides of the cone. It is also known as the vertex angle. The value of the apical angle determines the shape of the cone - a smaller apical angle will result in a more acute cone, while a larger apical angle will produce a more obtuse cone.

Does a cone have a right angle?

It could. If the nose is a right angle, it would be wide but a cone.

What is produced when you slice a cone at different angles?

When a cone is sliced parallel to the base then the shape produced is a circle. If the cone is sliced at an angle so that the cut goes completely through the cone then an ellipse is produced. If the cut is made perpendicular to the cone's base then the shape produced is a parabola.


What is the parallel cross section of a cone?

The answer depends on the angle at which the axis of the cone intersects the cross-sections.


What is an apex angle?

Apex (Angle)The apex is the pointed tip of a cone. The apex angle is the angle between the lines that define the apex, as shown to the left.


How do you find the height of a cone with a diameter of 20 meters?

Cannot. If you do not know the angle of the cone, you cannot determine its height.
