\n" ); document.write( "~~~~~~~~~~~~~~~~~~~~\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "
\r\n" );
document.write( "If the area of a square is 70 cm^2, then its side  \"a\"  is  a = \"sqrt%2870%29\" cm.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then the radius of the circle is  r = \"sqrt%28%28a%2F2%29%5E2%2B%28a%2F2%29%5E2%29\" = \"sqrt%28%282a%5E2%29%2F4%29\" = \"a%2Fsqrt%282%29\" = \"sqrt%2870%29%2Fsqrt%282%29\".\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then the area of the circle is  \r\n" );
document.write( "\r\n" );
document.write( "    area = \"pi%2Ar%5E2\" = \"pi%2A%2870%2F2%29\" = \"35%2Api\" = \"35%2A3.14\" = 109.9 cm^2  (approximately).    ANSWER\r\n" );
