Does a cylinder have to have a circular 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.
How many lines of symmetry does a circular cone have?
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.
If a right circular cone is intersected by a plane only at its vertex what figure it is?
A point.
If a right circular cone intersects a plane that runs parallel to the edge of the cone the resulting curve is?
The "conic section" that is produced when a right circular cone intersects a plane that runs parallel to the edge of the cone is a parabola. In the case where the plane also intersects the vertex of the cone, the parabola becomes two intersecting lines.
If a right circular cone intersects a plane that runs parallel to the edge of the cone the resulting curve will be an?
A Parabola.
What are three circular passages each in a different plane of space?
The name 'manifold' is used to describe such a construct. Assuming that the three circular spaces are indeed connected. The three planes need not be orthogonal - that is at right angles to each other.
What are the three circular passages each in a different plane of space?
The three semicircular canals are found in the inner ear and are used by the body to detect changes in position in relation to gravity.
What faces does a cone have?
A plane circular face and a curved shape which, if flattened out would be a sector of a circle.A plane circular face and a curved shape which, if flattened out would be a sector of a circle.A plane circular face and a curved shape which, if flattened out would be a sector of a circle.A plane circular face and a curved shape which, if flattened out would be a sector of a circle.
Can three points that define a plane also define a different plane?
No, only one UNIQUE Plane.
What is the base of CONE?
A plane circular shape.
Is aflat circular surface a plane?
Yes
What describes the base of cylinder?
A circular plane surface
What are the four kinds of parabolas?
Conic Sections are figures that can be formed by slicing a three dimensional right circular cone with a plane. There are different ways to do this, and each way yields a different figure. These figures can be represented on the graph as well as algebraically. The four conic sections are circles, ellipses, parabolas, and hyperbolas.
What geometric shape has 1 circular base?
A sphere intersected by a plane, An circular ellipsoid intersected by a plane, A cylinder, A cone, and many more shapes, some of which don't even have a name!
What is the figure called formed by the intersection of a right circular cone and a plane that lies parallel to the edge of the cone?
A parabola is the figure formed by the intersection of a circular cone and a plane that lies parallel to the edge of the cone. (the cone does not have to be a right [90°] circular cone).
Does a cylinder have to have a circular 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.
The line or plane upon which a figure is thought of as resting?
The line or plane upon which a geometric figure is thought of as resting is called the base. A three-dimensional figure with a circular base and the top meeting at a vertex; it resembles a funnel cone.
