Where, r represents the radius of the circle, θ is the angle between sector arcs, and π is a mathematical constant. Before we start learning more about the sector, first let us learn some basics of the circle. With this sector area calculator, you'll quickly find any circle sector area, e. Properties of a sector A sector of a circle is defined by the region bounded by two radii (plural for radius) of a circle and the arc they intercept. g. Area of sector is the amount of space enclosed within the boundary of a sector. The area of a sector is a fraction of the area of the circle. Apr 18, 2023 · Example 1: Find the area of the shaded region of a circle by using the area formula of the sector if the value of the radius is 8 cm and \theta is 60 o. For a radius of 20 units and a central angle of 162 degrees, the area calculates to 180π units squared, making the correct answer C. A slice of pizza is a real world example of a sector. To find the area of the shaded sector, use the formula: According to the diagram in the question OE is the radius The central Aug 3, 2023 · What is a sector of a circle – learn how to find its area and perimeter with formulas and solved examples The key to finding the area of this shaded part is the same as finding the area of any sector: you need to know the circle’s radius (or diameter) and the measure of the central angle that defines the sector. To find the area of a shaded sector: Get the radius and central angle. For example, for a shaded sector with a radius of 9 units and a central angle of 120 degrees, the area is 27π square units. What is a Circle? A circle is a locus of points equidistant from a given point located at the centre of the circle. How do you find the area of a shaded sector? The area of a shaded sector can be calculated by the same method we calculate the area of a sector. It only covers a small portion of the entire circle's surface. The region inside the portion of the **circle **formed by two radii and an arc is known as the area of a sector. Explore and learn more about the area of a sector formula, with concepts, definition, examples, and solutions. The area enclosed by two radii and the corresponding arc in a circle is called a sector of a circle. In geometry you learned that the area of a circle of radius \ (r \) is \ (\pi r^2 \). . Then, we apply the fraction based on the angle of the shaded sector to find its area. 1. com The area of a sector calculator calculates the central angle of the circle either in degrees or radians. Area of a Sector: “The area of a sector is the space inside the circle generated by two radii and an arc” Its defining characteristic is its central angle. See Related Pages In Summary An area of a sector is a portion of the area of a circle that is bounded by two radii and an arc. Oct 12, 2017 · To find the area of a shaded sector of a circle, we first calculate the area of the circle using the formula A = πr2. In this short article, we'll: Provide a sector definition and explain what a sector of a circle is. Before we determine how to find the area of a circular sector, let’s start by recalling the terminology for the parts 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. Reveal some real-life examples where the sector area calculator may come in A sector is a region that is bounded by two radii and the arc of the circle that lies between the radii. The sector is a A slice of pizza is a sector; a window pane divides a circular window into sectors.
