Total surface area (TSA) of cone (given radius and slant height)
Formula
S
total surface area
r
radius
l
slant height
Formula description
A cone is a three-dimensional geometric shape that tapers smoothly from a flat, usually circular base to a point called the apex or vertex. More precisely, it is the solid figure bounded by a plane base and the surface (called the lateral surface) formed by the locus of all straight line segments joining the apex to the perimeter of the base.
