In general: the circumference of a circle can be found using the following equation:
\n" ); document.write( " $\"c=2pi%2Ar\"$ where r is the radius. \r
\n" ); document.write( "\n" ); document.write( "We have r=5 so we have:
\n" ); document.write( " $\"c=2pi%2A5\"$
\n" ); document.write( "= $\"10pi\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "

\n" );
