an iron pipe 10 feet long has an internal diameter of 1 feet.
\n" ); document.write( " if the iron is 1/2 inch thick, find the volume of metal in the pipe
\n" ); document.write( ":
\n" ); document.write( "The overall diameter including the metal in the pipe will be 1 ft, 1 inch, 13\"
\n" ); document.write( "the radius will be 6.5\", find the overall volume in inches (10' = 120')
\n" ); document.write( " $\"V+=+pi%2A6.5%5E2%2A120\"$
\n" ); document.write( "V = 15927.87475 cu/in
\n" ); document.write( ":
\n" ); document.write( "Find the volume of the hollow area inside the pipe
\n" ); document.write( " $\"V+=+pi%2A6%5E2%2A120\"$
\n" ); document.write( "V = 13571.68026 cu/in
\n" ); document.write( ":
\n" ); document.write( "Find the volume of the metal
\n" ); document.write( "15927.87475 - 13571.68026 = 2356.1945 cu/in of metal
\n" ); document.write( " \n" ); document.write( "

\n" );
