Circle — basic elements?
Center, radius, chord, diameter, circumference.
Radius — definition?
Line from center to circle edge.
Diameter — relation to radius?
Diameter is twice the radius.
Circumference formula?
C = 2πr or πd.
Central angle — property?
Equals the measure of its intercepted arc.
Arc length — proportional to?
Central angle measure.
Sector area formula?
(Central angle/360°) × circle area.
Area of a disc?
πr², where r is radius.
Finding diameter from circumference?
d = C/π.
Finding radius from area?
r = √(area/π).
Circumference from radius?
C = 2πr.
Circle segment — definition?
Part of circle bounded by a chord and arc.
Proportionality in sectors?
Sector area ∝ central angle.
Real-world application?
Calculating material lengths, areas, or costs.
Chord — location?
Line connecting two points on the circle.
Key relationship?
Circumference/diameter = π.
