Tf the angular spacing of the solar disc is #alpha#. the diameter of the Sun is nearly #tan (alpha/2) # X (Earth-Sun distance), nearly...

Explanation:

If the angular spacing of solar disc is # 0.97995^o#, the diameter of

the Sun is nearly

#tan((0.97995/2)^o) AU#

#=0.008552 X 149597871 km#

#=1279344 km#.

There are telescopes that could measure angles correct to 0.001 ".
