Important topics for RS Aggarwal Class 10 Maths Solutions Chapter 16: Area of Circle, Sector and Segment
Area of a Circle
The area of a circle is always equal to πr2, where π=22/7 or ≈3.14 and r is known as the radius of the circle.
Circumference of a circle
The perimeter of any circle is always the distance that is covered by going around its boundary, which is also known as the circumference. The formula gives it 2πr
The segment of a circle
When a secant or a chord cut a circle, then the remaining portion of the circle is called the segment of the circle.
A sector of a circle
The region of a circle circumscribed by an arc and two radii is known as the sector of a circle. The smaller sphere is identified as the minor sector, and the larger sphere is termed the major sector. The angle confined between the two radii of the sector is known as the angle of a sector.
Length of an arc of a sector
The circumference of a circle and the angle of the sector is used to calculate the length of the arc of a sector, using the following formula:
where r is the radius of the circle, and θ is known as the angle of the sector.
Area of a Sector of a Circle
The following formula gives it
Ar = (θ/360°)×πr2
where ∠θ is the angle of this sector and r is its radius
Areas of Different Plane Figures
- Area of a square (side a) = a2
- Area of a rectangle = l×b, where l and b are the length and breadth of the rectangle
- Area of a parallelogram = b×h, where b is the base, and ‘h’ is the perpendicular height.
- Area of a trapezium =[(a+b)×h]/2, where a & b are the length of the parallel sides and h is the height
- Area of a rhombus = cd/2, where c & d are the diagonals of a rhombus
Exercise Discussion of RS Aggarwal Solutions for Class 10 Maths Chapter 16 Area of Circle, Sector and Segment
This exercise consists of 30 questions, out of which the first ten are based on finding the area and circumference of the circle. After this, some problems are about finding the length of the arc and area of the sector. Some questions are also based on finding the are of major and minor segments of the circle. Towards the end, some practical application-based questions are given about area and circumference.
This exercise has 27 questions in total. The first few questions are challenging levels of area and circumference. Later on, some problems are on finding the length of the arc and radii of the circle. There is also a question on the ratio of area and finding the ratio of the radius. Some figures were inscribed, and area calculation is asked. The practical issue on finding the length of pendulum and area swept by the minute and the hour hand is urged towards the end of the exercise.
