# It's swimming time!

Geometry Level 2

A swimming pool in the shape of a circle (as shown above) is to be built in a corner of a square. Before the construction begins, the contractor must know the values of $$a_1$$ and $$a_2$$. If you are the contractor, what is $$a_1+a_2$$?

Details:

1. $$20$$ feet is the radius of the circle.

2. Both $$a_1$$ and $$a_2$$ are perpendicular to one side of the square.
