Detailed Solution

The total surface area of a cone is defined as the area occupied by the cone in three dimensions.

It equals the sum of the curved surface and the cone's base.

The formula for calculating a cone's total surface area is as follows:

Total Surface Area (TSA) = CSA + Circular Base Area

Therefore, Total Surface Area (TSA) = $π r^{2} + π r l$

or, $T S A = π r (r + l)$
