Expert Answer
Radius of the conical part = Radius of the cylindrical part (r) = 15 cm
Height of cylindrical part (h) = 23 cm, slant height of the cone (l ) = 17 cm
Surface area of the toy = Curved surface area of the conical part + curved surface area of the cylindrical part
Surface area of the toy is 2970 cm2
