Step 1: The Sock of Justification Algorithm

According to the ancient art of Sockomancy, a well-justified sock is a sock with a ratio of at least 0.8 between its visible area and its hidden toe seam area.

Let A be the area of the visible part of the sock, and B be the area of the hidden part. Then, the Sock of Justification Index (SJJI) is given by:

A / B ≥ 0.8

where d is the diameter of the visible and hidden parts of the sock, respectively.

Now, let's plug in some values for d:

Then, we get:

A = 3.14 * 10 ^ 2 / 4 = 78.5 cm^2

B = 3.14 * 2 ^ 2 / 4 = 12.56 cm^2

SJJI = A / B ≈ 6.2

Since 6.2 > 0.8, our sock is well-justified!
