HELP ME PLEASE. ASAP. Use the given information to complete parts I and II. In your final answer, include all calculations. Mars has an approximate diameter of 6.794 · 10 9 millimeters. The sun has a diameter of 1.391 · 10 6 kilometers.

Part I: Given that for every one kilometer there are 1,000,000 millimeters, which unit of measurement should be used to best represent the lengths of the sun and Mar's diameters?

Part II: Use estimation to approximate how many times greater the sun’s diameter is than planet Mars’s.
