Use the given information to complete parts i and ii. in your final answer, include all calculations.

planet earth has an approximate diameter of 1.2742 · 10 10 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 earth's diameters?

part ii: approximate how many times greater the sun's diameter is than planet earth's.

The unit of measurement which should be used to best represent the lengths of the sun and Earth's diameters is Km.

Step-by-step explanation:

The diameter of sun= 1.391×10⁶ Km

The diameter of earth= 1.2742×10¹⁰ mm = 1.2742×10⁴ Km

As 1 Km= 10⁶mm

The sun's diameter times greater than earth=

1.391×10⁶ Km÷ 1.2742×10⁴Km= 109 times

The diameter of Sun is about 109 times the diameter of the Earth.
