Representation of data — practice question

A uniform solid cone has base radius $0.4\text{ m}$ and height $4.4\text{ m}$. A uniform solid cylinder has radius $0.4\text{ m}$ and weight equal to the weight of the cone. The cone and cylinder are joined together so that the cone’s base and one circular end of the cylinder touch, with their circumferences matching exactly. The combined body is in equilibrium with its circular base resting on a plane that is inclined at $20^{\circ}$ to the horizontal (see diagram).
