This solution can be cleaned up even further by putting getContextFunc into function thusly:
Function.prototype.inContext = function(context){
var func = this;
return function(){
return func.apply(context, arguments);
};
};

So that when you want to call it you can simply say:
getRemoteCircumference: function(url) {
$.getJSON(url, this.getCircumference.inContext(this));
}

@Brandon Sure you can, but you will not be able to use this in getCircumference cause it will run in the context of AJAX request object. There is a difference between mathObj.getCircumference() (calling object method) and mathObj.getCircumference (passing function reference as callback) this is what probably get you confused

I might be missing something but couldn’t you just use:

$.getJSON(url, mathObj.getCircumference));
