Question

9 the approximate circumferences of earth and saturn are shown. how many times as great is the circumference of saturn as the circumference of earth? the circumference of saturn is × 10 - km. saturns circumference is about times as great as the circumference of earth.

Explanation:

Step1: Identify the circumferences

The circumference of Earth $C_{E}=401\times 10^{3}\text{ km}=401000\text{ km}$, and the circumference of Saturn $C_{S}=365882\text{ km}$.

Step2: Calculate the ratio

We want to find $\frac{C_{S}}{C_{E}}=\frac{365882}{401000}\approx 0.9124$.

Answer:

The circumference of Saturn is about $0.9124$ times as great as the circumference of Earth.
