You have got as much as you can get from the information you have provided. In order to determine the radius you need additional information.

Yes, use the graph to figure out the radius. Start at the circle's center and move along a line parallel to the x-axis until you hit the edge of the circle. The radius is equal to the number of x's you moved from the center to the circle. Remember to square it in the equation (r2).
