Pentagon Inscribed In A Circle...

Ok. I know how to find the area of, like, a pentagon. But in this problem is wants me to find the area of the courthouse....like outside the pentagon.

So on a problem like this, do I follow through with steps to find the area of a pentagon and go from there?

Question:

The center of the pentagon in VA is a courtyard in the shape of a regular pentagon. The pentagon would be inscribed in a circle with radius of 300 ft. Find the area of the courtyard.
