Sunlight passing through a pinhole in a piece of paper casts an image of the Sun, as shown. The image size depends on the distance from the pinhole to the floor. If the paper with the pinhole is held about 100 cm above the floor, the diameter of the solar image is about 1 cm. A 1-cm-diamieters coin will just fit over the image (making it easy to measure!). That means about 100 end-to-end coins would fit between the floor and the pinhole. What does this tell you about how many Suns would fit between Earth and the Sun?

-9.22 was the answer I got and it is saying it's wrong. I also tried 1.44E1, -1.44E1, -1.32E1
The diameter of our disk-shaped galaxy, the Milky Way, is about 1.0×105light-years. The distance to the Andromeda galaxy, which is the spiral galaxynearest to the Milky Way, is about 2.5 million light-years. If a scale modelrepresents the Milky Way and Andromeda galaxies as dinner plates 20 cm indiameter, determine the distance between the centers of the two plates.
please include illustrations, i’m having trouble visualizing the main idea.. Thank you! ?
