--description--

Let $R(a, b, c)$ be the maximum area covered by three non-overlapping circles inside a triangle with edge lengths $a$, $b$ and $c$.

Let $S(n)$ be the average value of $R(a, b, c)$ over all integer triplets $(a, b, c)$ such that $1 ≤ a ≤ b ≤ c < a + b ≤ n$.

You are given $S(2) = R(1, 1, 1) ≈ 0.31998$, $S(5) ≈ 1.25899$.

Find $S(1803)$ rounded to 5 decimal places behind the decimal point.
