The are of the circle is 89.42 sq.inch. What is the circumference?
\n" ); document.write( "Find the radius using the area:
\n" ); document.write( " $\"pi%2Ar%5E2\"$ = 89.42
\n" ); document.write( " $\"r%5E2%29\"$ = $\"89.42%2Fpi\"$
\n" ); document.write( "r = $\"sqrt%2889.42%2Fpi%29\"$
\n" ); document.write( "r = 5.335
\n" ); document.write( ":
\n" ); document.write( "Find the circumference
\n" ); document.write( "C = 2*pi*5.335
\n" ); document.write( "C = 33.5214 inches \n" ); document.write( "

\n" );
