# Hey ant, I just want a word for you: the word is stop!

Geometry Level 4

In the figure shown above $$ABC$$ is a right triangle with $$\angle B = 90^\circ$$, $$AB=10-\pi$$ and $$BC=6$$. There is a semi-cylinder with radius $$1$$ and its axis is perpendicular to $$AB$$. That little ant in point $$A$$ must scape to point $$C$$ soon! What is the length of shortest way for him to going to his nest in point $$C$$?
