My brother reached out to me with a math problem. He has many hobbies, one of which is growing coral - a very slow process. In order to successfully keep track of how each coral is doing, he wanted 3D printed ovals with numbers on them. Because he wanted to be able to see how each coral was doing both from the front of the aquarium (where it is generally viewed from) and from the top (when cleaning or rearranging the aquarium), he wanted to place the ovals in the aquarium at an angle so that it would appear to be a circle when viewed from the front or the top. If he wants to oval to appear to be a circle with a 1-inch diameter, how tall should the oval actually be? If you're not sure how to start this, I recommend drawing pictures of the oval when viewed from multiple different directions.
