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

Km.

Part II

109 times

Step-by-step explanation:

Part 1

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

Part II

Diameter of the Sun= 1.391×10⁶Km

Diameter of Earth = 1.2742×10¹⁰ mm= 1.2742×10⁴Km

∴ 1 Km= 10⁶ mm

Now divide the sun diameter by earth diameter to know how many times the sun is bigger than earth.

How many times sun is bigger than earth= 1.391×10⁶÷1.2742×10⁴= 1.09×10²= 109 times

Hope it has answered your question.
