Circumference (entire arc length) of ANY circle: 2ꙥr\r\n" );
document.write( "Arc length of this circle's 90o angle: 5ꙥ inches\r\n" );
document.write( "Fraction of this circle's circumference equal to this arc length: \"90%2F360\" \r\n" );
document.write( "We then get:  \r\n" );
document.write( "          Radius, or
