Q:

How many edges does a cylinder have?

A:

Quick Answer

A cylinder technically has two curved edges, but in mathematics, an edge is defined as a straight line. Therefore, a cylinder actually has no edges, no vertices and two faces.

Full Answer

Cylinder originates from the Greek word "kulindros," meaning "roller" or "tumbler." It is a basic geometric shape, defined by its axis and enclosed surface area. In differential geometry, a cylinder's properties are more broad. When its cross section is an ellipse, parabola or hyperbola, a cylinder is called an elliptic, parabolic or hyperbolic cylinder, respectively.

Everyday uses of a cylinder are containers, the piston chamber in engines and bullet chambers.

    What is a chord in math?

    A:

    A chord is a straight line that connects two points on the curve of a circle. Unlike a secant, which is a line that extends infinitely in both directions, a chord is confined to inside the circle.

    What is the directrix of a parabola?

    A:

    The directrix of a parabola refers to a straight line that is drawn perpendicular to the axis of symmetry of a parabola. This line does not touch the parabola at any point. In addition, it is a horizontal line if the axis is vertical.

    How do you find the surface area of a cube?

    A:

    The surface area of a cube can be found by finding the length of any of the cube's edges, then multiplying that length by itself, then multiplying its product by six. This equation can be written as A=6e^2, where e stands for the length of any of the cube's edges.

    Why are parallel lines important?

    A:

    Parallel lines are important in mathematics because they are at the base of several conjectures involving angles in geometry. Drawing a line, called a transversal, through a pair of parallel lines forms three different types of angles that have known mathematical properties.
