So in school, I am doing a " planet paper roll comparison " So the scale of the diameter of one planet is 0.943cm or something.. How do I measure it on paper?
To measure the diameter of a planet on paper, you need to convert the scale to a size that is more practical for your project. Here's how you can do it:
1. Determine the actual diameter of the planet: Start by finding the actual diameter of the planet you are measuring. Let's say the actual diameter is 12,742 kilometers (for Earth).
2. Convert the actual diameter to centimeters: Convert the actual diameter from kilometers to centimeters by multiplying it by 100,000. In this case, the diameter of Earth would be 1,274,200,000 centimeters.
3. Determine the scale size: Now, based on your scale of 0.943 cm, you need to determine how many centimeters on paper will represent the actual diameter of the planet. Divide the actual diameter (in centimeters) by the scale size. Using the example scale size, the result would be approximately 1,350,076,038.
4. Mark the measurement on paper: With the scale determined, use a ruler or a measuring tape to mark the appropriate distance on your paper. In this example, you would mark a little over 1.35 billion centimeters on the paper.
By following these steps, you should be able to accurately measure the diameter of the planet on your paper based on the given scale.
