It's been a long time since I've attended school, over 33 years ago. So my question may seem basic to many here. I wish to calculate the partial volume of a cylinder for my excel spreadsheet project. The formula I've found is attached. (unable to type it)

But I do not fully understand this formula. Particulalry the R sq cos -1 section. Could somebody please explain how I use cos

Thank You
