How can you find the area of major segment using area of minor segment?

Answer

  1. Answer:
  2. ar(major segment)=area of circle-area of minor segment.
  3. Step-by-step explanation:
  4. to find the area of major segment we have to subtract the area of minor segment from area of circle.

How can you find the area of major circle segment using minor circle segments?

What Is the Formula for Area of the Segment of a Circle? The area of the segment of the circle (or) minor segment of a circle is: (θ / 360o) × πr2 – (1/2) r2 sin θ (OR) r2 [πθ/360o – sin θ/2], if ‘θ’ is in degrees. (1/2) × r2θ – (1/2) r2 sin θ (OR) (r2 / 2) [θ – sin θ], if ‘θ’ is in radians.

How do you find the major and minor segment of a circle?

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 major segment and minor segment?

A segment is a region bounded by a chord of a circle and the intercepted arc of the circle. A segment with an intercepted arc less than a semicircle is called a minor segment. A sector with an intercepted arc greater than a semi-circle is called a major segment.

How do you find the area of a section of a circle?

Area of a Sector of Circle = (θ/360º) × πr2, where, θ is the angle subtended at the center, given in degrees, and ‘r’ is the radius of the circle. Area of a Sector of Circle = 1/2 × r2θ, where, θ is the angle subtended at the center, given in radians, and ‘r’ is the radius of the circle.

How do you find the area of a minor sector?

The formula for sector area is simple – multiply the central angle by the radius squared, and divide by 2: Sector Area = r² * α / 2.

How do you find the area of the major segment?

(a) The area of the minor segment when angle θ and radius r are given: Area of segment = area of sector AOBC ± area of ΔAOB = 1 2r2θ ± 1 2r2sinθ = 1 2r2(θ − sinθ) Now the area of the major segment = area of circle − area of the minor segment = 1 2r2(2π − θ + sinθ)

What is the difference between minor segment and major segment?

The segment smaller than the semi-circle is called the minor segment and the segment larger than the semi-circle is called the major segment. (a) The area of the minor segment when angle θ and radius r are given: Area of segment = area of sector AOBC ± area of ΔAOB = 1 2r2θ ± 1 2r2sinθ

What is the area of the minor segment of a circle?

Area of the minor segment = area of sector O A B – area of Δ O A B. = 117.75 – 97.31 = 20.44 square cm. Area of the circle = π r 2. = 3.1415 × ( 15) 2 = 3.1415 × 225 = 706.5 square cm. Area of the major segment = area of the circle – area of the minor segment. = 706.5 – 20.4 = 686.1 square cm.

How do you find the height of a minor segment?

r– √r2– (c 2)2 gives the height of the minor segment Many formulas are given for finding the approximate area of a segment. Two of the common methods are: Method-I: A = 2hc 3 + h2 2c = h 6c(3h2 + 4c2)
