EDUCATION
Introduction:
NCERT Class 10 Maths Chapter 12, "Areas Related to Circles," takes students on an exploratory journey into the intricacies of circles and their related concepts. From understanding the properties of circles to exploring the areas of different geometric figures, this chapter provides a solid foundation in geometry. In this blog, we'll delve into the detailed solutions provided by NCERT for the exercises in Chapter 12, presented in a concise and easily understandable format.
Understanding Circles:
Circles are more than just round shapes; they are fundamental geometrical figures with unique properties.
Properties of Circles:
A circle is a set of all points in a plane that are equidistant from a fixed point called the center.
The distance from the center to any point on the circle is called the radius.
The distance across the circle passing through the center is called the diameter, which is twice the radius.
Areas Related to Circles:
This chapter explores various concepts related to circles, including:
Areas of Sectors and Segments:
A sector is a portion of the circle enclosed by two radii and an arc.
A segment is the region bounded by a chord and the arc subtended by the chord.
Formulas for calculating the areas of sectors and segments are provided and applied to solve problems.
Areas of Combinations of Plane Figures:
Problems involving the areas of combinations of circles, triangles, rectangles, and other polygons are solved using appropriate formulas and principles.
Perimeter of Figures:
The perimeter of different figures formed by combining circles, triangles, rectangles, etc., is calculated by adding the lengths of their respective sides.
