RD Sharma Class 10 Chapter 15 (Areas Related to Circles) Solutions


RD Sharma Class 10 Chapter-15 ‘Areas Related to Circles’ require you to have a prior understanding of some basic concepts of circles, such as the area and the perimeter of a circle. Moving forward, you will learn to find the area of a sector and a segment with the help of respective formulas.

These formulas will also come to play when you find the areas of some combined plane figures. For instance, you will come across questions that ask you to find the area of drain covers, flower beds, table covers, and window designs.

Formulas of Areas Related to Circles Class 10 | RD Sharma

  1. Circumference of a circle = 2πr
  2. Area of a circle = πr2
  3. Length of an arc of a  sector of a circle with radius r and angle 𝛉 = (𝛉/360) x 2πr
  4. Area of a sector of a circle with radius r and angle 𝛉 = (𝛉/360) x πr2
  5. Area of the segment of a circle = Area of the corresponding sector - Area of the corresponding triangle
