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?

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.

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.
