How do you measure circles
WebWhat is the measure of ∠BOA and ∠AOE in the circle shown below? Solution Since BE is a straight line (diameter of the circle) then, ∠BOA + AOE = 180° (x + 50) ° + (x + 10) ° = 180° 2x + 60°= 180° Subtract 60° on both sides. 2x = 120° By dividing both side by 2, we get x = 60° Now substitute. (x + 50) ° = 60° + 50° = 110° (x + 10) ° = 60° + 10° WebHow to Calculate the Area The area of a circle is: π ( Pi) times the Radius squared: A = π r2 or, when you know the Diameter: A = (π/4) × D2 or, when you know the Circumference: A = C2 / 4π Example: What is the area of a …
