You can put this solution on YOUR website!
Since the diameter is 18 inches, the radius is \"r=d%2F2=18%2F2=9\" inches. So \"r=9\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"V=pi%2Ar%5E2%2Ah\" Start with the volume of a cylinder formula.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"V=pi%2A%289%29%5E2%2820%29\" Plug in \"r=9\" (the radius) and \"h=20\" (the height).\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"V=%283.14159265%29%289%29%5E2%2820%29\" Replace \"pi\" with \"3.14159265\" (note: Use more digits of \"pi\" to get better accuracy).\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"V=%283.14159265%29%2881%29%2820%29%29\" Square \"9\" to get \"81\".\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"V=5089.380093\" Multiply \"3.14159265\", \"81\" and \"20\" to get \"5089.380093\" (this value is approximate).\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"V=5089.38\" Round to the nearest thousandth.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the approximate volume is about 5089.38 cubic inches.\r
