16 wrz 2022 · In geometry you learned that the area of a circle of radius \(r \) is \(\pi r^2 \). We will now learn how to find the area of a sector of a circle. A sector is the region bounded by a central angle and its intercepted arc, such as the shaded region in Figure 4.3.1.
Sectors with angle measures in degrees. A sector is the interior of a circle between two radii. sector radius radius θ. . There are 360 ° in a full circle. The central angle measure θ of a sector is between 0 ° and 360 ° , inclusive. Every sector has a fraction of the area of the full circle.
When the angle subtended at the center is given in degrees, the area of a sector can be calculated using the following formula, area of a sector of circle = (θ/360º) × πr 2, where, θ is the angle subtended at the center, given in degrees, and r is the radius of the circle.
11 mar 2023 · To calculate the area of a sector, start by finding the central angle of the sector and dividing it by 360. Next, take the radius, or length of one of the lines, square it, and multiply it by 3.14. Then, multiply the two numbers to get the area of the sector.
15 cze 2022 · A sector of a circle is the area bounded by two radii and the arc between the endpoints of the radii. If r is the radius and \widehat{AB} is the arc bounding a sector , then the area of the sector is \(A=\dfrac{m\widehat{AB} }{360^{\circ}}\cdot \pi r^2\).
Free online area of a sector calculator. Calculate the area of any sector given its radius and angle in degrees. Supports different metrics like inches, feet, yards, cm, mm, meters, km.
