A toy in the form of cone of radius 3.5 cm mounted on a hemisphere of same radius. The total height of the toy is 15.5 cm, find the total surface area of toy.

Answer

Total surface area of toy   Curved surface area of cone   surface area of hemisphere

Curved  surface area of cone
Where , Height

And hence,        (by using formula )

Therefore C.S.A. of cone

Surface area of hemisphere

Hence T.S.A of toy
