## FAQs on Circles: Exercise 10.1 Video Lecture - Mathematics (Maths) Class 10

 1. What is the formula to calculate the circumference of a circle?
Ans. The formula to calculate the circumference of a circle is C = 2πr, where C is the circumference and r is the radius.
 2. How is the area of a circle calculated?
Ans. The area of a circle is calculated using the formula A = πr^2, where A is the area and r is the radius.
 3. What is the relationship between the diameter and the radius of a circle?
Ans. The diameter of a circle is equal to twice the radius. In other words, d = 2r, where d is the diameter and r is the radius.
 4. How do you find the radius of a circle if you know the circumference?
Ans. To find the radius of a circle if you know the circumference, you can use the formula r = C/2π, where r is the radius and C is the circumference.
 5. Can you find the area of a circle if you only know the diameter?
Ans. Yes, you can find the area of a circle if you only know the diameter by first calculating the radius (r = d/2) and then using the formula A = πr^2 to find the area.
