The embly consists of a copper hemisphere connected to an aluminum cylinder into which a hole has been drilled parallel to its axis. Determine the total m in grams of this composite solid if the m densities for aluminum and copper are 2700 kg/cubic meter and 8900 kg/ cubic meter, respectively. The copper hemisphere is 15 mm in radius. The cylinder has a height of 50 mm. The hole is 6 mm in radius and its cylinder has a height of 25mm and the cone attached to it is 10mm.
