To make the study process easier and seamless, we provide the students with an option of PDF download. This provides the liberty to learn and revise from the Class 10 Maths Revision Notes Chapter 12, anytime, anywhere, the students wish to.
The students can also get the hardcopy printed, which comes in handy when the students are studying. This also eliminates the need to open the web every time while studying.
Chapter 1 - Real Numbers. Chapter 2 - Polynomials. Chapter 4 - Quadratic Equations. Chapter 5 - Arithmetic Progressions. Chapter 6 - Triangles. Chapter 7 - Coordinate Geometry. Chapter 8 - Introduction to Trigonometry.
Chapter 9 - Some Applications of Trigonometry. Chapter 10 - Circles. Chapter 11 - Constructions. Chapter 13 - Surface Areas and Volumes. Chapter 14 - Statistics. Chapter 15 - Probability. After covering the concepts of area and perimeter of various polygons, areas related to circles chapter deals with the areas and perimeter of circles, segments, and sectors have been explained.
The chapter is divided into multiple sections. The first section covers the areas and perimeters of circles. Secondly, it covers the area and perimeter of Segments and Sectors. Lastly, the problems related to the area and perimeters of combinational figures are dealt with. The usage of the formula of area and perimeter of the circle and the same analytical skill is vital for this part of the chapter.
The types of problems covered in Chapter 12 Maths Class 10 are finding radii of a circle that covers the area or perimeter of the sum area or perimeter covered by two other circles, finding the area of rings, and also the calculation of distance covered in the given the number of revolutions.
The formula for finding the area of sector and segment has been used in Class 10 Areas Related to Circle in the form of application-based sums. The part of the circular region enclosed by the two radii and the corresponding arc is called the sector of the circle. The part of the circular region enclosed between a chord and the corresponding arc is called the segment of the circle. The segment is classified as a minor segment and a major segment. The major segment covers a larger area corresponding to the minor segment.
Similarly, the sector is classified into minor and major where the major sector covers a larger area. The area and perimeter significantly depend on the angle subtended by the arc at the centre of the circle. When applicational problems are to be solved, the ability to pull out the angle subtended is crucial. For example, the angle subtended by a minute and hour hand at a certain time in the wall clock is repetitive. Also, a lot of questions are based on how the circle is divided equally, thus the technique to find the angle of each equally divided arc is to be known by the student for earning better marks.
These are asked in the forms of segments by umbrella or sectors when a regular polygon is inscribed in a circle. Although it may seem easy, Chapter 12 Class 10 Maths can easily cause students to make silly mistakes. So, practice is very significant for avoiding losing marks in a section where the possibility of scoring a hundred per cent is pretty high.
Areas related to Circle Class 10 Solutions provide problems for practice as well. Areas of Combinations of Plane Figures involves a lot of analytical and critical thinking as the type of question asked in the CBSE Boards from this section can not be Ch 8 Maths Class 10 All Formulas Teams predicted. This section mostly involves calculating the area of various designs and patterns using many plane figures and polygons. Mastering the formulas for finding the area of fundamental polygons is also to be concentrated by the student during the exam.
