A **circular sector** (also **circular cutout** ) is in the geometry of the partial surface of a circular area , of a circular arc and two circle radii is limited (as opposed to by an arc and a chord "limited circle segment / circuit

*section*"). Viewed from above, this area looks like a piece of cake .
