Is Delaware the only state where part of its boundary is the arc of a perfect circle?
No. If the arc is sufficiently small, almost every state in the world has a part of its boundary which is the arc of a perfect circle. Edit: The curved border divides Delaware and Pennsylvania, so PA also has an arc as part of its boundary. The 12 mile curve also crosses into the border with New Jersey...
