\n" ); document.write( "\"C=pi%2Ad\" Start with the circumference of a circle formula\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"C=3.14%2A28\" Replace \"pi\" with 3.14 (this is approximate) and plug in \"d=28\" (the given diameter)\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"C=87.92\" Multiply\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the circumference is about 87.92 inches
\n" ); document.write( "
