The sum of the areas of two circles which touch each other externally is \( 153\pi \). If the sum of their radii is 15, find the ratio of the larger to the smaller radius.

OABC is a square where O is the origin and AB = 1. Consider the set of points S = (x_i, y_i) in the square such that x_i + y_i ≤ 1.

Let P(x₁, y₁) and Q(x₂, y₂) be two such points. Two operations addition (+) and multiplication (·) on S are defined as:

P + Q = (x₁ + x₂ − x₁x₂, y₁y₂)

P · Q = (x₁x₂,   y₁ + y₂ − y₁y₂)
