Outside diameter is $\"12+%2B+1%2F2+%2B+1%2F2=13\"$ $\"inches\"$
\n" ); document.write( "The volume of the pipe (converting all units to inches),
\n" ); document.write( " $\"V=%28pi%2F4%29%2A%28D%5Bo%5D%5E2-D%5Bi%5D%5E2%29%2AL\"$
\n" ); document.write( " $\"V=%28pi%2F4%29%2A%2813%5E2-12%5E2%29%2812%2A10%29\"$
\n" ); document.write( " $\"V=%28pi%2F4%29%2A%28169-144%29%28120%29\"$
