    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
