The area of a circle is 49π, find it's circumference, in terms of π
\n" ); document.write( " $\"pi%2Ar%5E2+=+49pi\"$
\n" ); document.write( "divide both sides by pi
\n" ); document.write( " $\"r%5E2\"$ = 49
\n" ); document.write( "r = $\"sqrt%2849%29\"$
\n" ); document.write( "r = 7
\n" ); document.write( ":
\n" ); document.write( "C = $\"2pi%2A7\"$
\n" ); document.write( "C = $\"14pi\"$ \n" ); document.write( "

\n" );
