Historical Origins & Formula Derivation
The cone surface area formula has its roots in ancient Greek geometry, with key contributions from mathematicians like Archimedes. The modern formula for total surface area of a cone is derived from combining the base area (a circle) and the lateral (curved) surface area (a sector of a circle). The standard formula used is:
Total Surface Area = πr(r + l)
where:
r = base radius
l = slant height
