 Cylinder Formulas  Dr. Math FAQ
 A cylinder is a surface generated by a family of all lines parallel to
a given line (the generatrix) and passing through a curve in a plane (the
directrix). A right section is the curve formed by the intersection of the
surface and a plane perpendicular to the generatrix. The parallel bases of
a cylinder may form any angle with the axis.
More commonly, a cylinder includes the solid enclosed by a
cylinder and two parallel planes. The region of either of the parallel
planes enclosed by the surface is called a base of the cylinder. The
perpendicular distance between the planes of the bases is the height of
the cylinder. The line segment cut on any of the generating lines by the
two parallel planes is called a lateral edge.

 Cylinder Height, Area, Volume
 Why does the volume of a cylinder get larger as the radius gets
larger and the height gets smaller?
 Cylinder Volume and Surface Area
 How does one make a cylinder that holds the greatest volume if
the entire surface area is 600 cm squared?
 Cylinder Problem
 Is it possible to construct two cans with different volumes but the
same surface area?
 Maximizing the Volume of a Cylinder
 I need to maximize the volume of a rightcircular cylinder that fits
inside a sphere of radius 1 m.
 Applied Max/Min Problems
 Find the largest possible volume of a right circular cylinder
that is inscribed in a sphere of radius r.
 Maximizing the Volume of a Cylinder
 Find the dimensions of the cylinder of maximum volume that can be
inscribed in a cone having a diameter of 40 cm and a height of 30 cm.
Show that the maximum area of the cylinder is 4/9 the volume of the
cone.

capacity that uses the least amount of tin?
 Calculus: Rate of Change in
Volume
 The radius of a right circular cylinder is decreasing at the rate
of 4 feet per minute, while the height is increasing at the rate of
2 feet per minute. Find the rate of change in the volume when the radius
is 2 feet and the height is 6 feet.
