A cut through a right circular cylinder that is perpendicular to its altitude yields a circular cross-section.
A right circular cylinder that is cut on a plane not perpendicular to its altitude but also but also not parallel to its altitude will yield an ellipse whose minor axis is the diameter of the cylinder.
Trivial cases of a set of parallel lines, a single line, or the empty set occur when the cut is parallel to the altitude, externally tangent to the cylinder, or does not intersect the cylinder, respectively.

How many parallel lines in a cylinder 2?
A cylinder includes an infinite number of parallel lines. Every line in the curved surface is parallel to every other one and perpendicular to the two ends. . "A cylinder 2" is meaningless. You would have to look at the homework you're trying to get the answer for to see what cylinder 2 means.
How can you tell if a graph is a function?
A graph is a function if every input (x-value) corresponds to only one output (y-value). One way to check for this is to perform the vertical line test: if a vertical line intersects the graph at more than one point, the graph is not a function.
What is the formula for finding the area of base of a cylinder?
The circumference of a regular cylinder is the circumference of its circular face. C = pi * D (diameter of the cylinder) C = pi * 2r (or C = 2(pi)r)
The height of a cylinder is 10 inches and the volume is 146 cubic inches - what is the radius of this cylinder?
Using the formula for the volume of a cylinder (V = πr^2h), and substituting the given values, we can find the radius. Rearranging the formula to solve for the radius gives us r = √(V / (πh)). Plugging in the values, we get the radius as √(146 / (10π)) ≈ 2.15 inches.
How do vertical transformations differ from horizontal transformations?
Vertical transformations involve shifting the graph up or down, affecting the y-values, while horizontal transformations involve shifting the graph left or right, affecting the x-values. Vertical transformations are usually represented by adding or subtracting a value outside of the function, while horizontal transformations are represented by adding or subtracting a value inside the function.
