# Challenge 376: Circumcircle Challenge

What is the exact area of the circle that passes through all three vertices of this triangle?

In triangle ABC, AC = 2 units, the angle at A is 60^{o}, and the angle at B is 45^{o}.

The **circumcircle** of a triangle is the circle that passes through all 3 vertices of that triangle.

Find the **exact** area of the circumcircle of triangle ABC.
