Here is a frustum of a cone. The diagram shows that the frustum is made by removing a cone with height 3.4 cm from a solid cone with height 6.8 cm
and base diameter 7.6 cm.
3.4cm The frustum is joined to a solid hemisphere of diameter 7.6 cm
to form the solid S shown here. Solid S
The density of the frustum is 2.3g/cm
The density of the hemisphere is 4.6g/cm
3.4cm
3.4cm
Calculate the average density of solid S.
-7.6cm
-7.6cm
Your final line must say, Average density = ... g/cm
