FAQs on 02 - Areas Related To Circle - Part 2 (Combination Of Plane Figure) - Class 10 - Maths Video Lecture

1. What is the formula to find the area of a circle?
Ans. The formula to find the area of a circle is A = πr^2, where A represents the area and r represents the radius of the circle.
2. How can I find the circumference of a circle if the diameter is given?
Ans. To find the circumference of a circle when the diameter is given, you can use the formula C = πd, where C represents the circumference and d represents the diameter.
3. Can the area of a circle be equal to its circumference?
Ans. No, the area of a circle cannot be equal to its circumference. The area represents the space enclosed by the circle, while the circumference represents the distance around the circle. The two values are distinct and have different units of measurement.
4. What is the relationship between the radius and diameter of a circle?
Ans. The radius and diameter of a circle are related by the formula d = 2r, where d represents the diameter and r represents the radius. The diameter is always twice the length of the radius.
5. How can I find the area of a sector of a circle?
Ans. To find the area of a sector of a circle, you can use the formula A = (θ/360)πr^2, where A represents the area, θ represents the central angle of the sector in degrees, and r represents the radius of the circle.
