The total surface area of a cone is the total area that the cone occupies in two dimensions, including the area of the circular base and the area of the curving surface. Cone is a three-dimensional structure having a circular base where a set of line segments, connect all of the points on the base to a common point called apex. A cone can be seen as a set of non-congruent circular discs that are stacked on one another such that ratio of the radius of adjacent discs remains constant. You can think of a cone as a triangle which is being rotated about one of its vertices. There is a predefined set of formulas for the calculation of curved surface area and total ... Surface Area of a Cone ? There are two surfaces that make up the total surface of the cone - the lateral (or curved) surface and the base. The surface area of the cone is the total area covered by these surfaces. Alright, so what's formula for the surface area of a cone ? Here, we will learn about the surface area of the cone , including the formulas for Total Surface Area and Curved Surface Area, with the help of solved examples.
