Can I create a custom WP_Query using lat/lon and near radius?

I’m wanting to create a custom loop that populates Places (gd_place cpt) based on lat/lon. I’ve tried this so far but it doesn’t work:

$places = new WP_Query(array(
	'post_type' 		=> 'gd_place',
	'sgeo_lat'			=> '34.989220800000005',
	'sgeo_lon'			=> '-85.3525126'
));

if ( $places->have_posts() ) :

	while ( $places->have_posts() ) : $places->the_post();
	
		echo '<h2>'.get_the_title().'</h2>';
	
	endwhile; wp_reset_postdata();
	
endif;

Is there something I’m missing?

Also, would like to filter these results by changing the near radius value to 30(miles) instead of the default setting (15).

Any help here would be appreciated, thanks!
