-------------------
For a sphere:
Vol+=+4pi%2Ar%5E3%2F3
Vol of a sphere r = 100 cm = 4pi%2A100%5E3%2F3
Vol of a sphere r = 99 cm = 4pi%2A99%5E3%2F3
That leaves the shell vol = %284pi%2F3%29%2A%28100%5E3+-+99%5E3%29
1/2 of that for a hemisphere is
= %282pi%2F3%29%2A29701 cc
=~ 62205.63 cc
= 62.206 liters
