The inside volume is
\n" ); document.write( "\"V1+=+pi%2Ar%5E2%2Ah+=+pi%2A0.4%5E2%2A10+=+1.6pi\" cubic meters
\n" ); document.write( "---------------
\n" ); document.write( "The outside volume is
\n" ); document.write( "\"V2+=+pi%2Ar%5E2%2Ah+=+pi%2A0.5%5E2%2A10+=+2.5pi\" cubic meters
\n" ); document.write( "\"V2+-+V1+=+0.9pi\" cubic meters
\n" ); document.write( "1 cubic meter = 1,000,000 cc
\n" ); document.write( "Vol = 0.9*piE6 cc
\n" ); document.write( "=~ 2827433.4 cc
