In order to find the total space enclosed by the sector, we use thearea of a sectorformula. The area of a sector can be calculated using the following formulas, Area of a Sector of Circle = (θ/360º) ×πr2, where, θ is the sector angle subtended by the arc at the center, ...

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 × h w = width h = height We know w = 5 and h = 3, so: Area = 5 × 3 = 15Example...
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 angle, the larger is the area of the sector. The following diagrams give the formulas for the area of circle and the area of sector....

The formulas for the area of a circular sector and arc length are A=12r^2θ and s=rθ , respectively. (r is the radius and θ is the angle measured in radians).Let r= 10 centimeters. Write the area and arc length as functions of θ. What is the domain of each function? Use a...
Sectors are also found on hard drives in computers. However these “sectors” are slightly different to the ones we do in Mathematics, as they are actually not a full sector, but part of a math sector that is between two circular “tracks”. ...
Diameter: A parallel line runs from one side of the circle to the other, passing through the center point. A sector is part of a circle you can meet after creating an arc and its two radii. The area of a sector is: ∅/360° (πr²) ...
After knowing the area of the circle formula when radius, diameter, and circumference are given, it’s time to find the area of the circle when the sector is given. A sector is a portion of a circle, sometimes referred to as a wedge. When two radii are drawn from the center of a ...
