Question

A sphere (diameter 70mm) is placed centrally on the top hexagonal face of a hexagonal prism (base edge 25mm, height 50mm). Two of the base edges of the prism are parallel to V.P. The common axis is perpendicular to H.P. Draw the isometric projection of the combination of solids. Show the common axis and indicate the direction of viewing. Give all the dimensions.
