What is the radius of the circle? A. R=8 B. R=4 C. R=1 D. R=7

4 is the correct radius of question in the figure...

omg what happend to your question? if you could edit this question i can

step-by-step explanation:

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.
