Maybe, maybe not.
Either way, there's no reason to lose what may be a good friendship, and if you're concerned about her liking you as more than a friend, drop some hints about how you like this other girl and maybe even ask her for advice. She'll probably get the idea (then again, maybe not.)
I have heard that "will you help me with my homework?" is a sign that a girl likes you just a friend and not as anything more.
