Part A
Jupiter has a diameter of 142,984 kilometers. Assume that a basketball with a diameter of 25 centimeters represents the
planet Jupiter. Find the scale (ratio) between Jupiter and the basketball. Then use this ratio to find the scaled diameter of
the other planets.
For example, to find what Saturn\'s size would be after adjusting it to scale, follow these steps. Let the scaled diameter of
Saturn be d centimeters. If Jupiter\'s diameter, 142,984 kilometers, is scaled to 25 centimeters, Saturn\'s diameter of
120,536 kilometers will be scaled to about 21 centimeters:
143,984

Next, look at the table of real-world spherical or nearly spherical objects, and choose the object that best matches the
scaled diameter of each planet.
Use this table and the process shown above to complete the table.
