As per the question we can draw the diagram, Given:The radius of the conical part and the hemispherical part is same (i.e.,3.5 cm)Height of the hemispherical part, r =3.5=27​Height of conical part, h=15.5−3.5=12 cmSlant height(l) of conical part = r2+h2​= (27​)2+122​=449​+144​=449+576​​=4625​​=225​Total surface area of toy = CSA of conical part + CSA of hemispherical part= πrl+2πr2= 722​×27​×225​+2×722​×27​×27​=214.7
