Answer:

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

Curved surface area of cone = πrl

Where r=3.5cm, Height =15.5−3.5=12cm

And hence, l=12.5cm (by using formula l

2

=h

2

+b

)

Therefore C.S.A. of cone =π×3.5×12.5

=137.5cm

2

Surface area of hemisphere =2πr

2

=2×π×(3.5)

2

=77cm
