请问May一个关于规律的问题，因所问题目在库中找不到，请忽略所选题目，关注图片中题目，谢谢。理解了图中题目的常规做法，想问一个扩展的问题，如同条件二的情况，知道了圆柱体中油面的面积，在确认了油面的长和宽情况下，如果知道了油的深度(即图中所画的圆中的BP)，是否这个圆柱体的圆面大小就确定了?这可以是一个定律吗？

请May老师解答～ 老师，您回复我的这一题，关于圆心角 和 圆周角，我有几个问题想问： 1. ABC是一个优弧，优弧的圆心角是怎么看的呢？为什么是∠BOC，而不是∠AOC呢？ 2. 此图中，（优弧）弧ABC 和 （劣弧） 弧AC是否有同一个圆心角 和 同一个圆周角呢？ 如果不是，老师可否分别把此图中 优弧与劣弧的圆心角和圆周角画一下？ 2. 优弧ABC所对应的圆周角 是∠E（我用红笔加上去的那一个）吗？
