**Answer:**

The formula for calculating the circumference (C) of a circle, C = πD or C = 2πR, is simple if you know the circle's diameter (D) or radius (R). But what do you do if you only know the circle's area? Like many things in math, there are multiple solutions to this problem. The formula C = 2√πA is designed to find a circle's circumference using the area (A). Alternatively, you can solve the equation A = πR2 in reverse to find R, then plug R into the circumference equation. Both equations provide the same result.

Lines of symmetry is when all points touch each other so, #1 Is 5 Lines #2 Is No Because it has no lines that touch. #3 Is 4 Because its a rectangle and rectangles have 4 points so that would be 4 cause 4 points equals 4 lines. #4 Is No because Triangles have no lines. These Answers are for the first questions 1-4
