Question

Let's explore how Earth compares in size to the sun.

a) The diameter of the sun is 1.4 million kilometers, and the diameter of Earth is 12,700 kilometers.Write each of these diameters in scientific notation in kilometers.

b) How many times larger is the sun's diameter than Earth's diameter?

Answer 1

A. 1.4 million Km = 1.4 x 10^6 Km

12,700 Km = 1.2 x 10^4 Km

B. (1.4 x 10^6 Km)/(1.2 x 10^4 Km)= 1.167 x 10^2

The sun diameter is 116.7 times greater than earth's diameter
