The volume of a cylinder is given by

Let
and 
The new volume becomes

So, the new volume is 8 times the original volume. In fact, volume scales linearly with the height and quadratically with the radius.
Let
N--------> <span>members of the club
we know that
($192/(N+2)=3.20
192=(N+2)*3.20
3.20*N+6.40=192
3.20*N=192-6.40
N=185.60/3.20
N=58
the answer is
58</span>
