Thearea of sectorof a circle is the space enclosed within the boundary of the sector. A sector always originates from the center of the circle. Let us learn more about thearea of sector formula, andhow to find the area of a sector in radiansand degrees. What is Area of Sector of a ...
A sector is like a “pizza slice” of the circle. It consists of a region bounded by two radii and an arc lying between the radii. The area of a sector is a fraction of the area of the circle. This area is proportional to the central angle. In other words, the bigger the central...
Arc of a Circle:An arc of a circle is referred to as a curve that is a part or portion of its circumference. Acute centralangleswill always produce minor arcs and small sectors. When the central angle formed by the two radii is 90o, the sector is called a quadrant because the total ...
1【题目】5Given that the area of a circle with radius 10 cm is equal to the area of asector with centralangle 40°, then the radius of the sector iscm. 25 Given that the area of a circle with radius 10 cm is equal to the area of a sector with centralangle 40°, then the radiu...
Area = ½(a+b) × h h = vertical height Circle Area = π× r2 r = radius Ellipse Area = πab Sector Area = ½ × r2×θ r = radiusθ = angle in radians Note: h is at right angles to b Example: What is the area of this rectangle? The formula is: Area = w ...
sector.where C S is the arc length of the sector.Notice that when finding the area of a sector, you are actually finding a fractional part of the area of the entire circle. The fraction is determined by the ratio of the central angle of the sector to the "entire central angle" of...
The Area of A Sector Calculator is used to help you find the area of a sector of a circle. FAQ What Is The Area of Sector Formula? The following is the calculation formula for the area of a sector: Where:A = area of a sectorπ = 3.141592654r = radius of the circleθ = central...
