Also known as disc, filled circle, circular area
平面上以圓為界的區域
A disk is a flat, round shape that includes everything inside a circle, including the circle's edge itself. It matters in mathematics and everyday life because many objects—from plates to wheels to coins—are disk-shaped, making it a fundamental form for understanding geometry and designing practical things.

在几何中,一个圆盘(disk 或 disc)是由平面中一个圆(circle)围成的区域。一個圓只包含邊界,而一個圓盤包含内部區域。在度量幾何與凸分析中,圓盤是凸集,因為每兩點之間的直线點都落在該點集合中;但是圓不是凸集,因為它是中空的。
