If the distance measurement used for the angular size method is inaccurate by 2%, what is the resulting error in the calculated physical size?

Answer

The calculated physical size will also be off by 2%

The physical size calculation is highly sensitive to distance measurement accuracy; any percentage error in the distance translates directly into the exact same percentage error in the resulting calculated physical size of the planet.
