If a regular hexagon with side length 10 3 is inscribed in a circle, how much
larger is the area of the circle than that of the hexagon?

Solve for the sides or angles indicated. If there are no solutions, write “No Triangle”. If
there is more than one solution, give both. Any time a formula is used, show the
formula with values substituted. Round sides to the nearest hundredth and angles to
the nearest second.
