The arc of a circle is defined as the part or segment of the circumference of a circle. A straight line that connects the two ends of the arc is known as a chord of a circle. If the length of an arc is exactly half of the circle, it is known as a semicircular arc.
27 gru 2013 · The formula, A = ½• r²• (θ - sin (θ)), computes the area defined by an arc and the chord connecting the ends of the arc (see blue area of diagram). Choose units and enter the following: The calculator returns the area (A) in square meters.
Learn how to calculate the area of a sector of a circle using different formulas for degrees and radians. A sector is the portion of a circle between two radii and an arc.
30 lip 2024 · This arc length calculator is a tool that can calculate the length of an arc and the area of a circle sector. This article explains the arc length formula in detail and provides you with step-by-step instructions on how to find the arc length. You will also learn the equation for sector area.
Learn how to calculate the area and arc length of a sector or a segment of a circle. Find the formulas, examples and interactive diagrams for different angles and radii.
The area of the segment can be seen graphically to be the difference between the area of the sector (defined by r and `theta` in the equation above) and the the area of the triangle defined by r and `theta` above -- or more properly the summation of the area of the two right triangles with sides r, a, and b in the left picture.
30 lip 2024 · Find the area of any circle sector using the formula r² × α / 2, where r is the radius and α is the central angle in radians. Learn how to derive the formula, see examples and special cases, and explore real-life applications of sector area.
