A model is a cone of base radius 7 cm and height 24 cm fitted exactly into the open top of a hollow cylinder of radius 7 cm and height 24 cm (cone points up, base flush with cylinder rim). The OUTER surface to be painted = cylinder outer curved + cylinder bottom circle + cone outer curved (the top of the cylinder is fully covered by the cone's base, so that rim circle is hidden). In ${\text{cm}}^2$ (π = $\frac{22}{7}$): (CSA = curved surface area, TSA = total surface area)
