Formulas for a segment of a circle area

1. Formula given radius and central angle. A segment = 0.5 * r² * (α – sin(α)) Where does this formula come from?
2. Formula given radius and height. Asegment= r² * arccos((r-h)/r) – (r-h) * √(2 * r * h – h²) where h is the height of a segment, also known as sagitta.

How do you find the minor segment of a circle?

The area of the segment of the circle (or) minor segment of a circle is:

1. (θ / 360o) × πr2 – (1/2) r2 sin θ (OR) r2 [πθ/360o – sin θ/2], if ‘θ’ is in degrees.
2. (1/2) × r2θ – (1/2) r2 sin θ (OR) (r2 / 2) [θ – sin θ], if ‘θ’ is in radians.

How many segments are in a circle?

A circle may be divided into two or more segments. A segment is the region of a circle bounded by a chord and an arc. If the circle is divided into two segments, the bigger portion is called the major segment and the smaller portion is called the minor segment. The semi-circle is the biggest segment of any circle.

### What is a segment in math?

segment. noun (ˈsɛɡmənt) maths. a part of a line or curve between two points. a part of a plane or solid figure cut off by an intersecting line, plane, or planes, esp one between a chord and an arc of a circle.

What is the formula of major and minor segment?

Hence the area of the segment (minor) can be calculated by subtracting the area of the triangle from the area of the sector. The area of the major segment can be calculated by taking the area of the minor segment from the total area of the circle.

What is the formula of major segment class 10th?

Any chord AB divides circle into two parts. The bigger part is known as major segment and smaller one is called minor segment. Area of major segment OAQB = πr2 — area of minor segment APB.

#### How do you find the equation of a circle in a chord?

Given the radius and distance to center In case, you are given the radius and the distance of the center of circle to the chord, you can apply this formula: Chord length = 2√r2-d2 , where r is the radius of the circle and d is the perpendicular distance of the center of the circle to the chord.

What is segment math?

How do you write a segment of a circle?

In geometry, a circular segment (symbol: ⌓), also known as a disk segment, is a region of a disk which is “cut off” from the rest of the disk by a secant or a chord.

## How do you calculate the area of a circle segment?

find the area of the whole sector

• find the area of the triangle within the sector
• subtract the area of the triangle from the area of the sector
• What is the formula for circle sector?

– A circular sector is the portion of a disk enclosed by two radii and an arc. – A sector divides the circle into two regions, namely Major and Minor Sector. – The smaller area is known as the Minor Sector, whereas the region having a greater area is known as Major Sector.

What is the standard equation for a circle?

The Center: (4,2)

• Up: (4,2+5) = (4,7)
• Down: (4,2−5) = (4,−3)
• Left: (4−5,2) = (−1,2)
• Right: (4+5,2) = (9,2)
• ### What are the formulas for circles?

Circle Formulas: r is symbol for radius of circle. d is symbol for diameter of circle. c is symbol for circumference of circle. Circle formulas are: Diameter of circle = 2r; Circumference of circle = 2πr (where π = (frac{22}{7})) Area of circle = πr 2; Extended circle formulas: Length of arc = (frac{ϴ}{360⁰}) x 2πr (where ϴ
