This page examines the properties of a right circular cylinder. A cylinder has a radius (r) and a height (h) (see picture below). This shape is similar to a can. The surface area is the area of the top and bottom circles (which are the same), and the area of the rectangle (la...
The formula for the volume of a cone is one-third of the volume of a cylinder. The volume of a cylinder is given as the product of base area to height. Hence, the formula for the volume of a cone is given as V = (1/3)πr2h, where, "h" is the height of the cone, and ...
