The most basic shape in all ofgeometryis that of a sector cut out of themiddleof a circle. It possesses a variety of distinctcomponentsof its own. For example, thediameter, theradius, thecircumference, thesegment, and thesector. Figure 1: Illustration of a Sector Area of a Sector The to...
The above expression is also an area of a sector formula, but this time the central angle is measured in radians. Example 1: Area of a Sector of a Circle Using Degrees What is the area of a circular sector whose radius is 3 cm and the central angle is 45∘?Lesson...
If the area of a sector is known, and the angle (θ) subtended by the arc is known, the radius can be calculated by substituting the given values in the formula, Area of a Sector of a Circle = (θ/360º) ×πr2. For example, let us find the radius if the area of a sector...
The sector of a circle is a partition of that circle. A sector extends from the center, or origin, of the circle to its circumference and encompasses the area of any given angle that also originates from the center of the circle. A sector is best thought of as a piece of pie, and ...
The meaning of SECTOR is a geometric figure bounded by two radii and the included arc of a circle. How to use sector in a sentence.
Example: Janice needs to find the area of the red section of the circular table top in order to buy the right amount of paint. What is the area of the red section of the circular table top? Solution: Step 1:Find the area of the entire circle using the area formula A = πr2. ...
Find the Arc Length and the Area of a Sector of a Circle: Arc Length Example A circle has a radius of 12 inches and is intercepted by a central angle with a measure of π2. Find the arc length of this sector. Step 1: Note the radius and angle measure: radius: 12 inches Ang...
A Sector Area Calculator is a tool that helps to calculate the area of a sector, which is a part of a circle enclosed between two radii and an arc of the circle. The formula to calculate the area of a sector is given by: A = (θ/360) x πr^2 ...
The meaning of SECTOR is a geometric figure bounded by two radii and the included arc of a circle. How to use sector in a sentence.
A radiant electric heater (10) shaped substantially as a sector of a circle is disclosed. The heater may be used in an oven, for example a microwave oven (2) having a turntable (8) for supporting food items (32, 34, 36) in the oven cavity (6). The heater incorporates a heating ...
