the radius is half of the diameter, so d = 2r , or double the radius :)
The reason you got it wrong is because you solved for the side a instead of the angle Z, which was what the question asked you to solve for. You can find Z by doing cos Z = 12/35, which will get you cos Z = 0.343, and Z will be equal to about 70º.
