you can remember at my questions last year?

I mean the following Code (radius to coordinates), but unfortunately
it is written in Perl
my $radius = 20 ;
my $clat = 34.918 ;
my $clng = -89.8215 ;
my $PI = 3.141593 ;
my $d2r = $PI/180 ;
my $r2d = 180/$PI ;
my $lat = ($radius/3963) * $r2d ;
my $lng = $lat/cos($clat * $d2r);
my @points = ( ) ;
my $i = 0 ;
my $x = '' ;
my $y = '' ;
for ($i = 0 ; $i < 10 ; $i++)
{
$y = sprintf("%0.6f",$clng + ($lng * cos($PI * ($i/6)))) ;
$x = sprintf("%0.6f",$clat + ($lat * sin($PI * ($i/6)))) ;
push( @points, [$x,$y] ) ;
}
foreach $x ( @points )
{
print "$$x[0],$$x[1]\n" ;
}
