<PRE><B>Question 590793</B>
a storage tank consists of a hemisphere of diameter 4.7 m and a cylinder. 
the overall height of the tank is 16.5m.
find the capacity of the tank
:
The Radius: 4.7/2 = 2.35 m
:
Find the vol of the hemisphere: 
V = {{{2/3}}}*{{{pi*2.35^3}}}
V = 27.18 cu/meters
:
The height of the cylinder: 16.5 - 2.35 = 14.15
V = {{{pi*2.35^2*14.15}}}
V = 245.49 cu/meters
:
Total vol
27.18 + 245.49 = 272.67 cu/meters</PRE>
