Question:
The interior of a building is in the form of a cylinder of base radius 12 m and height 3.5 m, surmounted by a cone of equal base and slant height 12.5 m. Find the internal curved surface area and the capacity of the building.
Solution:
Height of the cone
Capacity (volume) of cone
Capacity (volume) of cylinder
Therefore,
Total capacity of building
Internal curved surface area of the building
