FAQs on Circle: Examples Video Lecture - Mathematics (Maths) Class 11 - Commerce

1. What is a circle?
Ans. A circle is a two-dimensional geometric shape that is perfectly round and consists of all points in a plane that are equidistant from a fixed center point.
2. What are the properties of a circle?
Ans. The properties of a circle include having a fixed center point, a constant radius that measures the distance from the center to any point on the circle, and a circumference that represents the total distance around the circle.
3. How do you calculate the circumference of a circle?
Ans. The circumference of a circle can be calculated using the formula C = 2πr, where C represents the circumference and r is the radius of the circle. Simply multiply the radius by 2 and then multiply it by π (pi), which is approximately 3.14159.
4. What is the relationship between the diameter and radius of a circle?
Ans. The diameter of a circle is twice the length of its radius. In other words, if you know the radius of a circle, you can find its diameter by multiplying the radius by 2. Conversely, if you know the diameter, you can find the radius by dividing the diameter by 2.
5. How do you find the area of a circle?
Ans. The area of a circle can be calculated using the formula A = πr², where A represents the area and r is the radius of the circle. To find the area, square the radius and then multiply it by π (pi), which is approximately 3.14159.
