how many (#) 0.45 inch spheres to fill a 3 inch dia. by 4 inch high cylinder ?
-------
# accommodated by the height:: 4"/(0.45) = 8.89;; round down to 8
----
# accommodated by the cross-section:
Cross-section of the cylinder: pi*1.5^2 = 7.07 in^2
Cross-section of a sphere:: pi*0.225^2 = 0.159
# accommodated by the cross-section = 7.07/0.159 = 44.45; round down to 44
========
Ans: # of spheres accommodated by the cylinder: 44*8 352k
