Total Surface Area of Cone
Total surface area of a cone is defined as the total area occupied by a cone in a three-dimensional space, i.e., the area of a curved surface and the area of the circular base. The formula for the TSA (total surface area) of the cone is given as follows:
where,
- “r” is the Radius of the Base of a Cone
- “l” is Slant Height of Cone
Surface Area of Cone
Surface Area of a Cone is the total area encompassing the circular base and the curved surface of the cone. A cone has two types of surface areas. If the radius of the base is ‘r’ and the slant height is ‘l’, we use two formulas:
- Total Surface Area (TSA) of the cone = πr(r + l)
- Curved Surface Area (CSA) of the cone = πrl
In this article, we will talk about the surface area of the cone, including the formulas for Total Surface Area and Curved Surface Area, with the help of solved examples.
