Answer:

12

Step-by-step explanation:

The equation of a circle with center in (h, k) and radius r has the form

(x - h)² + (y - k)² = r²

In this case, the given equation is

x² + y² - 144 = 0

We can add 144 to both sides to get

x² + y² - 144 + 144 = 0 + 144

x² + y² = 144

Then, 144 = 12², so

x² + y² = 12²

Therefore, the radius of the circle is 12.
