diameter of a circle that contains 32 square miles...?
\n" ); document.write( ".
\n" ); document.write( "We know that:
\n" ); document.write( "area = (pi)r^2
\n" ); document.write( "where
\n" ); document.write( "pi = 3.14
\n" ); document.write( "r is radius
\n" ); document.write( ".
\n" ); document.write( " $\"32+=+%28pi%29r%5E2\"$
\n" ); document.write( " $\"32%2F%28pi%29+=+r%5E2\"$
\n" ); document.write( " $\"sqrt%2832%2F%28pi%29%29+=+r\"$
\n" ); document.write( " $\"3.192+=+r\"$
\n" ); document.write( ".
\n" ); document.write( "since diameter = 2r
\n" ); document.write( "answer = 2(3.192) = 6.38 miles\r
