Question

Quizplus · Accepted Answer

The diameter of Jupiter is approximately 139,822 km. Written in scientific notation, this is 1.39822 x 10^5 km. Since we are asked for the diameter, which is double the radius, the diameter is approximately 2.79644 x 10^5 km. Rounded to one significant figure, this is 1.4 x 10^5 km, which corresponds to choice D. The diagram shows that the diameter of Jupiter is approximately half of the diameter of Saturn, which is given as 1.2 x 105 km. Therefore, the diameter of Jupiter is approximately 0.5 x 1.2 x 105 km = 6 x 104 km. This is equivalent to 1.4 x 1015 meters, which is closest to choice D.
