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 l²=h²+b²)

Therefore C.S.A. of cone = π×3.5×12.5

= 137.5cm²

Surface area of hemisphere =2πr²

=2×π×(3.5)²

=77cm²

Hence T.S.A of toy = 77+137.5

= 214.5cm²
