Answer:
200
Step-by-step explanation:
18 × 10 = 180
20 × 1 = 20
180 + 20 = 200
The diameter of a circle passes through the middle
(y-k)²=4p(x-h)
(h,k) is vertex
and since we got the y term squred, it is facing left or right
when p is positive, then focus is to right of veretx
p is distance from focus to vertex and from vertex to dirextix
y²=-x
(y-0)²=4(-1/4)(x-0)
vertex is (0,0)
p is negative so then focus to left of vertex
so the focus is (-1/4,0)
dirextix is x=1/4
That all cause u the length of the time
