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
