How exactly is this used? I need to have a dialog open up and ask the user for the center point of a circle and the radius...im fine with that...im fine with setting up the area in which the circle will go, but the only problem I have is how to draw the actual circle...The arguments for Arc are a rectangle and 2 points.....I set the top-left to x - radius and y - radius respectevly....What do I set the startPT and endPT to?
