You can put this solution on YOUR website!
circumference, C = \"pi%2Ad\" or C = \"2%2Api%2Ar\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "you have radius = 3, so use the second version:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "C = \"2%2Api%2A3\"
\n" ); document.write( "C = \"6%2Api\" --> exact solution.
\n" ); document.write( "--> C = 18.84955592 by evaluating on a calculator which rounds to 18.85 to the nearest hundredth.\r
