Answer:
530.66 cm^2
Explanation:
Equation: 3.14•13^2
13^2= 169
3.14•169= 530.66
(x-h)^2 + (y-k)^2 = r^2
(x-2)^2 + (y-0)^2 = (rt(5))^2
-h = -2
h = 2
k=0
Center(2, 0)
I think the answer is 175.
Hopefully this helps.
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
