Finding the Radius of a Circular Sector given Its Perimeter and Central Angle in Radians. ARC TO CHORD RATIO. Sector Area Calculator. Central Angle 

$$ \text {The area of the circle } = \pi \times radius^{2} $$ $$ \text {and the circumference circle} = 2 \pi \times radius$$ Now we can use of the angle is clearly delineated, therefore we can replace once around (2π) with the subtended angle and we get the formula we needed for the sector as follows: $$ Area = (\frac {Angle}{2}) \times radius^{2} $$ Let's take the example : radius is 7 cm

To recall, a sector is a portion of a circle enclosed between its two radii and the arc adjoining them. For example, a pizza slice is an example of a sector representing a fraction of the pizza.There are two types of sectors, minor and major sector. A minor sector is less than a semi-circle sector, whereas a major sector is a sector that is greater Area of a cyclic quadrilateral. Area of a quadrilateral. Area of a regular polygon.

Hence, required area A is given by = 10.26 cm 2 Example 6: The perimeter of a sector of a circle of radius 5.2 cm is 16.4 cm. Find the area of the sector. 2016-01-12 The formula for the area of a sector is (angle / 360) x π x radius2. The figure below illustrates the measurement: As you can easily see, it is quite similar to that of a circle, but modified to account for the fact that a sector is just a part of a circle. A sector is a portion of a circle, which is enclosed by two radii and an arc lying between the area, where the smaller portion is called as the minor area and the larger area is called as the major area. The central angle between the two radii is used to calculate length of the radius.

Hey, i have made a program that finds the area, anulus and (attempting) area of sectors in a circle, but i dont know how to use angles in C#. I was wondering if someone could give me a sample code for sectors and allow me to modify it?

For arcs, there are two options for calculating areas, namely Segment or Sector. The   Revision notes on 'Circles - Sector Areas & Arc Lengths' for the CIE IGCSE Maths exam. Designed by the expert teachers at Save My Exams.
