FAQs on Problem set on Circles Video Lecture - SSC CGL Tier 2 - Study Material, Online Tests, Previous Year

1. What is a circle and how is it defined in mathematics?

Ans. A circle is a two-dimensional geometric shape that is perfectly round and is defined as the set of all points in a plane that are equidistant from a fixed center point. In mathematics, a circle is typically represented by its center coordinates and radius.

2. What is the formula to calculate the area of a circle?

Ans. The formula to calculate the area of a circle is A = πr^2, where A represents the area and r represents the radius of the circle. The value of π is approximately 3.14159.

3. How can I find the circumference of a circle if I only know its diameter?

Ans. If you only know the diameter of a circle, you can find its circumference by using the formula C = πd, where C represents the circumference and d represents the diameter. The value of π is approximately 3.14159.

4. Can a circle have a negative radius?

Ans. No, a circle cannot have a negative radius. The radius of a circle represents the distance from its center to any point on its boundary. Since distance cannot be negative, the radius of a circle is always a non-negative value.

5. What is the relationship between the radius and diameter of a circle?

Ans. The diameter of a circle is always twice the length of its radius. In other words, the diameter is the longest chord that can be drawn within a circle, passing through its center. Therefore, the relationship between the radius (r) and diameter (d) of a circle is given by the equation d = 2r.
