Circumference & Area of a Circle
Circumference = Distance aroundoutside circle
Diameter and Radius of a Circle How did I get 12? diameter radius 12 6 Double the radius 6x2 =12
Circumference Circle What is the formula? Circumference = Pi times Diameter C = pd d 6 C = p (6) Round to nearest tenth C = 18.84955592… C = 18.84 C ≈ 18.8 units (un)
Area = Everything inside shaded (yellow) area
Area Circle What is the formula? Area = Pi times radius squared A = pr2 3x3 A = p (32) 3 r Round to nearest tenth A = p (9) A = 28.27433388… A = 28.27 A ≈ 28.3 units squared (un²)
