Given Radius of Earth 6378 km Radius of Sun 695950 km Im m

Given:

Radius of Earth = 6378 km

Radius of Sun = 695,950 km

I\'m mostly just unsure on the scale part... What does it mean \"convert these values on a scale of one to one billion\"?

Now, convert all of these values on a scale of 1:109 (that is, one to one billion): b. Calculate the diameters (not radin of the Earth and Sun in centimeters by this scale

Solution

It means you have to convert units from KM to billion cm

6378KM = 12756 KM diameter of Earth and 1391900 KM of Sun

Now, 1km =10^5 cm

So, 12756 KM = 12756 *10^5 cm = 1.2756 *10^9 cm or 1.2756 billion cm

With Sun it\' 13.919 billion cm
