The radius of the planet Uranus is approximately 4 times the size of the radius of Earth. What does this tell you about the volumes of these planets?

This tells you that Uranus is 15,792 which is making it 4 times Earth's radius.

Earth's radius is 3948 which tells you that is 1/4 the volume of Uranus.

Step-by-step explanation:

Earth volume is approximately V = (4/3) πr³, and

Uranus volume is approximately V = (4/3) π (4r) ³, or (4/3) π*64*r³

Comparing these two results, we see that the volume of Uranus is approximately 64 times greater than the volyume of Earth.
