The surface are of teh cone would be 62.4 squared cm. You would find the area by multipling the radius 6 (3x2) by 10.4 to get 62.4.
Directrix (directrix):
SA = π · r * L + π · r² where L is the slant height of the cone.
Directrix (directrix):
SA = π · r * L + π · r² SA = π ·3 * 10.4 + π ·3²
Directrix (directrix):
SA = π ·3 * 10.4 + π ·3² SA = 126.29
