What this Circles: Circumference and Area Made Clear quiz checks
- Diameter = 2 × radius, and radius = diameter ÷ 2.
- Circumference: C = πd = 2πr, measured in linear units.
- Area: A = πr², measured in square units.
- A semicircle has half the area; a quarter circle has one fourth.
- Doubling the radius quadruples the area.
