Box2d too much for Circle/Circle collision detection?

I'm using cocos2d to program a game and am using box2d for collision detection. Everything in my game is a circle and for some reason I'm having a problem with some times things are not being detected as a collision when they should be.

I'm thinking of rolling up my own collision detection since I don't think it would be too hard.

Questions are:

Would this approach work for collision detection between circles?
a. get radius of circle A and circle B.
b. get distance of the center of circle A and circle B c. if the distance is greater than or equal to the sum of circle A radius and circle B radius then we have a hit
Should box2d be used for such simple collision detection? There are no physics in this game.

I'm working on a 2D game in which I would like to do collision detection between a moving circle and some kind of static curves (maybe Bezier curves). Currently my game features only straight lines as the static geometry and I'm doing the collision detection by calculating the distance from the circle… >>> More
