How to Find the Diameter of a Circle from …

Web17 sep. 2024 · For any point on a circle, there is only one other point on the circle such that the line segment between the two points is a diameter. Thus, for part (a), the distance is 0. For part (b), you are on the right track - it is indeed a right triangle. WebThe area of an equilateral triangle with side length s is s²√3/4. Since we know the areas of these triangles, we can solve for their side lengths: s²√3/4=9√3. s²/4=9. s²=36. s=6. So the triangles have sides of length 6. And when follow a diameter of the circumcircle, we trace two sides of equilateral triangles.
