Cylinder and Cones:

Cylinders are like prisms, the only difference is that instead of having polygons for a bases it has a circles for a bases. In a right cylinder, the perpendicular segment that joins the two circular bases at its centers is called the altitude. The length of the altitude is called the height of the cylinder, denoted as h. The radius of the base is also the radius of the cylinder.


Cones are similar to pyramids, The only difference is that the instead of having a polygon for a base the base of a cone is a circle. In a right cone, the altitude of a cone has a length called the height, and is a segment that is perpendicular to the base from the vertex to the center of the base. The slant height of a cone is the segment from the vertex to the edge of the base.

Volumes of Cylinders and Cones:

Volume of Cylinders:
V = Bh = pr²h

Volume for Cones:

Lateral Area of Cylinder:
L.A. = ph = 2prh
