Calculate the angular diameter of Jupiter at the moment of its opposition if it is known that its linear diameter is 11.2 times larger

Calculate the angular diameter of Jupiter at the moment of its opposition if it is known that its linear diameter is 11.2 times larger than that of the Earth. The distance from Earth to Jupiter was 4.2 AU. e. The radius of the Earth is 6400 km.

decision
d = Dp; p = d / D = 11.2 * 2 * 6400 km / 4.2 AU * 1.5 * 10 ^ 8 km / AU. = 47 “.
