If you know the area of a circle, the circumference can be found using the formula
\n" ); document.write( " $\"C=4%28pi%29A\"$
\n" ); document.write( " where:
\n" ); document.write( " $\"A\"$ is the area of the circle
\n" ); document.write( " $\"pi\"$ is Pi, approximately 3.142
\n" ); document.write( "if $\"A=748cm%5E2\"$
\n" ); document.write( " $\"C=4%28pi%29A\"$
\n" ); document.write( " $\"C=4%28pi%29748\"$
\n" ); document.write( " $\"C=2992%28pi%29\"$
\n" ); document.write( " $\"C=9400.864\"$
\n" ); document.write( " $\"highlight%289400.864cm%29\"$ \r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
