A toy is in the f

Answer :

From the drawn figure, we have

Base radius, r = 3.5 cm

Height of the cone, h = 15.5 – 3.5

= 12 cm

We know that, Slant height of the cone,

= 12.5 cm

We also know that Inner surface area of the toy = Curved surface area of cone + Curved surface area of hemisphere

= 214.5 cm2

Hence, the total surface area of the toy is 214.5 cm2
