Question

select the correct answer. the orbital radius of venus is 0.72 au. what is this distance in kilometers? (one au is about 150 million kilometers.) a. 10.8 kilometers b. 10.8 million kilometers c. 108 kilometers d. 108 million kilometers

Explanation:

Step1: Set up conversion formula

Let $d$ be the distance in kilometers. We know that $1\ AU = 150000000$ kilometers and the radius of Venus is $0.72\ AU$. So $d=0.72\times150000000$.

Step2: Perform multiplication

$d = 0.72\times150000000=108000000$ kilometers. Since $108000000$ kilometers is $108$ million kilometers.

Answer:

D. 108 million kilometers
