<think> Okay, so I need to solve this geometry problem. Let me read it again carefully. The problem says: In triangle ABC, the circumcenter is O and the incenter is I. We are given that IA is perpendicular to OI, the circumradius is 13, and the inradius is 6. We need to find AB times AC, and the answer should be boxed....

<think> Okay, let's see. I need to solve this barrels problem. The goal is to maximize the water volume in the first barrel by throwing clay into any barrel, and the clay affects the pipes between barrels. Hmm. First, let me understand the setup. We have n barrels arranged in a row. Each barrel has an initial volume o...
