Can't get value from second join table in whereHas clause

i have to problem, i need to search if user is in specific radius. I have two join tables on users, address and search radius...query will received two param lat and log.

$query = Users::query();
$query->with('location', 'serach_area');
$query->whereHas('location', function ($query) use  ($latitude, $longitude) {
    $query->select('users_locations.latitude as latitude', 'users_locations.longitude as longitude', 'users_locations.user_id', 'search_area.radius s radius')
        ->selectRaw("(6371 * acos(cos(radians('.$latitude.')) * cos(radians(latitude)) * cos(radians(longitude) - radians('.$longitude.'))   sin(radians('.$latitude.')) * sin(radians(latitude)))) as haversine")
        ->having("haversine", "<", "radius");    });

I can't get search area.radius if I hard coded number, it works perfectly if anyone have any idea please commented
