Topics Covered in Exercise 11.1 Class 10 Mathematics Questions
NCERT solutions for class 10 maths chapter 11 ex 11.1 covers the topic of areas of sector and segment of a circle.
1. 
Areas of Sector and Segment of a Circle 

Areas of Sector and Segment of a Circle  The portion (or part) of the circular region enclosed by two radii and the corresponding arc is called a sector of the circle and the portion (or part) of the circular region enclosed between a chord and the corresponding arc is called a segment of the circle.
Areas of Sector  There are two types of sectors: 1. Major sector, 2. Minor sector

A major sector is defined as a sector that is greater than a semicircle.

A minor sector is defined as a sector that is less than a semicircle.
Formula of Area of Sector
You can use this formula to figure out how much space a piece of a circle covers. You can think of it as the total area of the circle.
Area of sector of a circle =θ/360∘×πr2,
where ‘r’ is the radius of the circle and ‘θ’ is the angle at the center of the circle.
Segment of a Circle  There are two types of segments: 1. Mejor segment, 2. Minor segment

A major segment is made from the major arc.

A minor segment is made from the minor arc.
Formula of Segment of a Circle
Area of segment of a circle = Area of the corresponding sector – Area of the corresponding triangle.
Area of segment = θ/360×πr2 − ½xr2 sinθ
Length of an arc of a sector of a circle with radius r and angle with degree measure is = θ/360∘× 2πr
