30 lip 2024 · With this sector area calculator, you'll quickly find any circle sector area, e.g., the area of a semicircle or quadrant. In this short article, we'll: Provide a sector definition and explain what a sector of a circle is. Show the sector area formula and explain how to derive the equation yourself without much effort.
A sector of a circle of radius r r r and angle θ \theta θ has points A and B on the circumference of the circle. AB forms a segment of the circle. The area of the segment is given by: Area of segment = area of sector − area of triangle ABC.
16 wrz 2022 · For a sector whose angle is θ in a circle of radius r, the length of the arc cut off by that angle is s = rθ. Thus, by Equation 4.3.1 the area A of the sector can be written as: A = 1 2 rs. Note: The central angle θ that intercepts an arc is sometimes called the angle subtended by the arc.
The area 𝐴 of a sector of a circle of radius 𝑟 that subtends an angle of 𝜃 rad is given by 𝐴 = 1 2 𝑟 𝜃 . The area 𝐴 of a segment of a circle of radius 𝑟 that subtends an angle of 𝜃 rad is given by 𝐴 = 1 2 𝑟 (𝜃 − 𝜃) s i n.
15 cze 2022 · If r is the radius and \widehat{AB} is the arc bounding a sector, then the area of the sector is \(A=\dfrac{m\widehat{AB} }{360^{\circ}}\cdot \pi r^2\). Figure \(\PageIndex{1}\) A segment of a circle is the area of a circle that is bounded by a chord and the arc with the same endpoints as the chord.
The segment R, shaded in the diagram above, is enclosed by the arc AB and the straight line AB.
