Area Related to Circles Class 10 Maths

In this chapter, you have studied the following points :
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 with degree measure θ is \frac{\theta}{360} \times 2 \pi r
4. Area of a sector of a circle with radius r and angle with degree measure θ is \frac{\theta}{360} \times \pi r^2
5. Area of segment of a circle = Area of the corresponding sector – Area of the corresponding triangle.
