This is the implicit equation of a cylinder: a point $(x,y,z)$ lies on the cylinder if it satisfies the equation. The important thing here is in fact that $z$ does not occur in the equation.
Sketch or use a graphing tool to view the graph of the cylindrical surface defined by equation z = y 2. z = y 2. When sketching surfaces, we have seen that it is useful to sketch the intersection of the surface with a plane parallel to one of the coordinate planes.
The picture below illustrates how the formula for the area of a cylinder is simply the sum of the areas of the top and bottom circles plus the area of a rectangle. This rectangle is what the cylinder would look like if we 'unraveled' it.

A cylinder is a surface made up of lines that are all parallel to a given line, passing through a given plane curve. So, for example, a right circular cylinder is made up of vertical lines all parallel to each other, passing through a circle. For more examples, see the board for the graphs of the cylinders C 1 and C
The figure above depicts the developmental figure of a cylinder whose base radius is r r and height is h. h. The surface area is equal to the sum of the areas of the two circular bases and the rectangular side. The area of each base is \pi r^2. πr2.
