Expert Answer:

internal CSA=CSA of the cylin portion+ CSAof the conical portion

=[22/7*(12)(12.5)]+[2*(22/7)*(12)*(3.5) ..(using the formulae for CSA of cylin and cone)

 

Capacity of the building

=vol of the con portion +vol of cylin portion

=[(1/3)(22/7)*(12)*(12)*(h)]+[(22/7)*(12)*(12)*(3.5)]...(using formulae for vol of cone and cylin)

where

h=straight height of the cone=
