RS Aggarwal Solutions for Class 10 Maths Chapter 16 Area of Circle, Sector and Segment


A sector of a circle is area bounded by two radii and the arc between the endpoints of the radii. The area of a sector is a fractional part of the area of the circle, just like arc length is a fractional portion of the circumference. The area of segment in a circle is equal to the area of sector minus the area of triangle. The segment of a circle is a region bounded by the arc of the circle and a chord. The area of segment in a circle is equal to the area of sector minus the area of the triangle. The chapter deals with the topic of “Area of Circle, Sector and Segment”. The segment of a circle is a region bounded by the arc of the circle and a chord. The concepts that are discussed include “motivate the area of a circle”; “area of sectors and segments of a circle”, problems based on areas and perimeter/ circumference of the given plane figures etc.
