What is circle segment area formula?
Formula To Calculate Area of a Segment of a Circle. Area of a Segment in Radians. A = (½) × r2 (θ – Sin θ) Area of a Segment in Degrees. A = (½) × r 2 × [(π/180) θ – sin θ]
How do I find the area of a segment?
- Area of Sector = θ × π 360 × r2 (when θ is in degrees)
- Area of Segment = ( θ × π 360 − sin(θ)2 ) × r2 (when θ is in degrees)
- L = θ × π180 × r (when θ is in degrees)
How do you find the area of a segment of a circle without angle?
Thus the equation of circle is x²+y²=r². The equation of the chord at ‘a’ distance from center is ax-ry- ar=0 or Y= a/r(x-r). the area of sector can be found by relating it to area of segment where the area of segment is found without the usage of angle made by the chord.

What is segment of a circle class 9?
A segment of a circle is defined as a region bounded by the chord and the corresponding arc lying between the endpoints of the chord. In other words, we can define it as a region of a circle, by breaking the circle through a secant of chord.
What is the area of minor segment of circle?
The area of the segment of the circle (or) minor segment of a circle is: (θ / 360°) × πr2 – (1/2) r2 sin θ (OR) r2 [πθ/360° – sin θ/2], if ‘θ’ is in degrees.
What is a segment of a circle class 9?
What is the area of segment PQR If Radius is 7cm?
Thus, the area of the segment PQR is 0.65625 cm2.
What is sector area?
Area of a circle is given as π times the square of its radius length. So if a sector of any circle of radius r measures θ, area of the sector can be given by: Area of sector = θ 360 × π r 2.
What is segment and sector of a circle?
The region between two radii of a circle and any of the arcs between them is called a sector. Segment: In geometrically, a line segment is a part of a line that is bounded by two distinct end points, and contains every point on the line between its end points.
What is length of segment?
Answer: The length of a line segment can be measured by measuring the distance between its two endpoints. It is the path between the two points with a definite length that can be measured. Explanation: On a graph, the length of a line segment can be found by using the distance formula between its endpoints.
What area of a circle whose radius is 7cm 1 point 22 3.14 154?
So, area of the given circle =π×7×7=49π
What is the formula of area of minor segment?
What is segment in class 9 circle?
What is the formula to find the length of a segment?
Line Segment Formula Now, let us see how to find the length of a line segment when the coordinates of the two endpoints are given. In this case, we use the distance formula, that is, D = √[(x2−x1 x 2 − x 1 )2 + (y2−y1 y 2 − y 1 )2].
What is equation of line segment?
Line Segment Formula As we know, a line segment has two endpoints. Now if we know the coordinates of the endpoints, then we can calculate the length of the line segment by distance formula. D = ( x 2 − x 1 ) 2 + ( y 2 − y 1 ) 2.
What is area of segment If radius is 7cm?
Since r=7. So, area of the given circle =π×7×7=49π
