Hi All
I am trying to calculate the segment area of a circle, but my unknown is the central angle.
As an example
A 500mm Dia circle with the bottom 30mm cut off....I need the area of the bottom 30mm, but, as I said , I don't have the central angle
I'd really appreciate anyones Geometry assistance, all I can find on the Net requires that central angle,
