The equatorial circumference of Earth is about ##4*10^4## kilometers. The equatorial circumference of Jupiter is about ##439,263.8## kilometers. About how many times greater is Jupiter‘s circumference than Earth’s?

About 11 times.

To find how many times greater the circumference of Jupiter is than the circumference of Earth, we divide Jupiter’s circumference by Earth’s circumference.

##4 * 10^4 = 40000## ##(439263.8km)/(40000km) = 10.981595##

We can round this to eleven.
