Select the correct answer.

The orbital radius of Uranus is 19.22 AU. What is this distance in kilometers? (One AU is about 150 million kilometers.)

A.

2,883,000 million kilometers

B.

2,883 million kilometers

C.

28 million kilometers

D.

2.8 million kilometers

"2,883 million kilometers" is the distance.

Answer: Option B

Explanation:

The radius of orbital of Uranus is = 19.22 AU

The unit of length or the distance from Earth to the Sun which is equal to approximately 150 million kilometers is known as "astronomical unit".

1 AU is about = 150 million kilometers

So the distance can be calculated by multiplying radius of orbital from one astronomical units:

150,000,000 x 19.22 = 2,883,000,000 or 2,883 million km.

The answer can also be in scientific notation form as follows:

19.22 AU = 19.22 * 1.5 * 10^8 km = 2883 * 10^6 Km.
