Viewed by: 5668 students WebSep 15, 2024 · We know that ABC is a right triangle. So as we see from Figure 2.5.3, sinA = 3 / 5. Thus, 2R = a sinA = 3 3 5 = 5 ⇒ R = 2.5 . Note that since R = 2.5, the diameter of the circle is 5, which is the same as AB. Thus, ¯ AB must be a diameter of the circle, and so the center O of the circle is the midpoint of ¯ AB.
