# The base of a cone with diameter 21 cm and slant height 12 cm is hemispherical. Find the total surface area of the solid.

## Given: A cone with hemispherical surface.Slant Height diameter Total surface area= Total surface Areaof cone + Total surface area of HemisphereTotal surface area of cone But since we have a hemispherical surface as be Total surface are of cone will be Total  surface area of hemisphere but since the base of cone hemisphere is some and total surface area will not consider any be area Total surface area of hemisphere in this case Total surface area = Total surface area of cone+ Hemisphere putting value of and
