WebCircles are 2D shapes with one side and no corners. The circumference is always the same distance from the centre - the radius. Sectors, segments, arcs and chords are different parts of a circle. WebA = π r 2. A=\pi r^2 A = πr2. A, equals, pi, r, squared. Number of degrees of arc in a circle. 360. 360 360. 360. A central angle in a circle is formed by two radii.
