WebIf is measured in degrees, then “the area of a sector of a circle formula” is given by Area of sector = θ 360 ∘ × π r 2 If is measured in radians, then “the area of a sector of a circle formula” is given by Area of sector = 1 2 × θ × r 2 Perimeter of sector = 2 r + θ 360 × 2 π r Area of Sector Formula: When Angle Is Not Given WebDec 8, 2014 · The circle ∘ is the symbol for composition of functions. In General, if you have two functions g: X → Y and f: Y → Z, then f ∘ g is a function from X to Z. For x ∈ X one has ( f ∘ g) ( x) = f ( g ( x)). In your case one has: f ( x) = 2 x − 1, g ( x) = 3 x + 2 and ( f ∘ g) ( x) = f ( g ( x)) = 2 ( g ( x)) − 1 = 2 ( 3 x + 2) − 1 = 6 x + 3. WebThere are two basic formulas to find the length of the chord of a circle: Chord length using perpendicular distance from the center = 2 × √ (r 2 − d 2 ).
