  a. the radius was how many feet? How many feet in a yard? Then how many feet in 2 yards? b. the diameter was how many feet? The radius is from the edge of the circle to the center. The diameter is edge to center to other edge, so it's twice as far. The diameter is twice the radius. So you can find the diameter if you double your first answer.
