Watch Your Head 2

Randy Weiss continued a mile down the road after finding Watch Your Head and is able to find another mathematically significant road sign.



Mr. Weiss breaks from the most traditional way of achieving pi on Road Sign Math with a new approach! Apparently this strategy was suggested to him from his brother.

$$\sqrt{2} + \sqrt{13-10} \approx 3.1463 \approx \pi$$

This sign is on northbound I-95 in Connecticut.
