Enter the equation of the circle described below.
Center (0,4), radius V3

(x)^2 + (y - 4)^2 = 3

(it could also be (x - 0)^2 + (y - 4)^2 = 3 but you can drop the zero by the x and just have it like: (x)^2 + (y - 4)^2 = 3)

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
