The circumference of a circle is,
\n" ); document.write( "\"C=2%2Api%2AR\"
\n" ); document.write( "The area of a circle is,
\n" ); document.write( "\"A=pi%2AR%5E2\"
\n" ); document.write( "\"A=pi%2A%28C%2F%282%2Api%29%29%5E2\"
\n" ); document.write( "\"A=C%2F%284%2Api%29\"
\n" ); document.write( "When \"C=12\",
\n" ); document.write( "\"A=12%2F%284%2Api%29\"
\n" ); document.write( "\"A=3%2Fpi\"
\n" ); document.write( "Do the same for the second circumference.
