Question

A right circular cone is intersected by a plane that passes through only one nape of the cone and is not parallel to an Edgar of the cone or the base, as in the picture below, what object is produced from this intersection

Answer 1

As it is given that the plane is not parallel to the base and passes through only one of the cones so

The object that will be produced will be an ellipse

A circle is produced when the plane is parallel to the base

So the correct option is (D)
