The principal subjects are discussed briefly in Class 10 Maths NCERT Exemplar Solutions of Chapter 12 Areas related to circles, including:
Circumference of the circle: A circle's perimeter is the linear distance travelled around the circle. The perimeter of a circle is known by a unique name, Circumference. The circumference multiplied by the diameter is given by the formula 2πr.
Area of circle: The circle area is πr^{2}, where r is the circle's radius and π = 22/7 or 3.14 (maybe used interchangeably for problem-solving purposes). Thus, an area of the circle is nothing but is the ratio of a circle's circumference to its diameter.
A Circle's Segment
A circular segment is a section of a circle "separated" from the portion of the circle by a secant or chord.
A circle's sector
A circle sector is the portion of a circle bounded by an arc and two radii. The smaller region is referred to as the minor sector, while the larger area is the major sector.
A Sector's Angle
The angle of a sector is defined as the angle formed by the sector's two radii.
The Angle of a Sector
A sector's angle is defined as the angle created by the sector's two radii.
L= (θ/360°) × 2πr
Where θ is the sector angle and r is the circle's radius.
