As given in the question, 12700 Km is equivalent to 1 cm on the given scale.
So, 1 Km is equivalent to 1/12700 cm. Thus, diameter of the sun (1.4 * 10^6 km) can be calculated as (1.4 * 10^6) / 12700 = 110.23 cm
Again, 1 Light year = 9.46 * 10 ^ 12 Km. So, on calculation, 4.24 light year is equal to 3.15 * 10^9 cm.
