what is the standard notation for the diameter of the sun

To work out the X coordinate you work out what one third of 6 - 0 is (which is 2) and to work out the Y coordinate you work out what one third of 8 - 4 is (which is around 1.3 you then add that to 4 and get 5.3). Therefore the answer is (2, 5.3) and when rounded to one figure its (2, 5).
