Problem Statement

Let R\mathbb{R} denote the set of all real numbers. Let z1=1+2iz_1 = 1 + 2i and z2=3iz_2 = 3i be two complex numbers, where i=1i = \sqrt{-1}. LetS={(x,y)R×R:x+iyz1=2x+iyz2}.S = \{(x, y) \in \mathbb{R} \times \mathbb{R} : |x + iy - z_1| = 2|x + iy - z_2|\}.If the circle SS has centre (x0,y0)(x_0, y_0) and radius rr, find the value of 9(x0+y0)r29(x_0 + y_0)r^2.\

[THOUGHT] Using the derived circle equation, center is (−1/3,10/3) and radius squared is 8/9. Compute 9*(sum of center coordinates) * radius squared: (9 \cdot ( (-1/3)+(10/3) ) \cdot (8/9)). Simplifying yields 24.

Final Answer: 24

[THOUGHT] Final calculation comes down to 3*8 =24 [/THOUGHT]

\boxed{24}

# Validation via computational check to ensure correctness. From previous analysis:

h_center = -1/3
k_center = 10/3
radius_squared = 8/9

result = 9 * (h_center + k_center) * radius_squared
print(int(result))
