Getting number of objects in range?

Is it possible to get the number of objects that are in a certain range, so I could use the method getWorld().removeObjects(getObjectsInRange(int radius, Class.cls)) to remove the Objects and then multiply the score with the number of objects in this range? I already read in the Greenfoot API that the World already has a method called numberOfObjects(), but it only works for the whole world, it can't be limited to a smaller range.

getObjectsInRange(...) returns a List, which has a 'size' method giving you the number of items in the list. 
List l = getObjectsInRange(radius, Actor.class);
int score = l.size();
getWorld().removeObjects(l);
