Question

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.

Answer 1

Answer:

Part 1

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.

Hope it has answered your question.
