Surface Area = Areas of top and bottom +Area of the side. Surface Area = 2(Area of top) + (perimeter of top)* height. Surface Area = 2(pi r 2) + (2 pi r)* h. In words, the easiest way is to think of a can. The surface area is the areas of all the parts needed to cover the can.
height of cone=6cm
slant height, L=√〈R²+H²〉
TSA=lateral Surface area of cone+ lateral surface are of hemisphere
