Q:
# How many edges does a cylinder have?

A:

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.

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.

Q:
## How do you find the equation of a secant line?

A:A secant line of a curve is a straight line connecting two points on the curve. The equation for a line is given by the formula y = mx + b, where m equals the slope of the line, and b equals the y intercept, or the point where the line crosses the y axis. Find the equation by first finding the slope, then plugging values for x and y into the formula and solving for b.

Q:
## What angle is zero degrees?

A:

Full Answer >**A zero degree angle appears as a straight line that travels from the point of inception to the right or positive side of a number line.**If the line travels both left and right from the point of inception, it is considered a 180 degree angle or straight angle.Filed Under: -
Q:
## What is a chord in math?

A:

Full Answer >**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.Filed Under: -
Q:
## What is the radiius of a circle?

A:

Full Answer >**The radius of a circle is the distance from the center of a circle to any point on its edge.**The word derives from the Latin word "radius," meaning a staff, a spoke or a stake of a wheel.Filed Under:
