FAQs on L2 : Area of Circle - Area Related to Circles, Maths, Class 10 Video Lecture

1. What is the formula for finding the area of a circle?

Ans. The formula for finding the area of a circle is A = πr^2, where A represents the area and r represents the radius of the circle.

2. How do I calculate the area of a circle if I know the diameter?

Ans. If you know the diameter of a circle, you can calculate the area by using the formula A = π(d/2)^2, where A represents the area and d represents the diameter of the circle. The radius is equal to half of the diameter.

3. Can you provide an example of calculating the area of a circle?

Ans. Sure! Let's say we have a circle with a radius of 5 cm. Using the formula A = πr^2, we can calculate the area as follows: A = π(5)^2 A = π(25) A ≈ 78.54 cm^2

4. Is the value of π constant for all circles?

Ans. Yes, the value of π (pi) is a mathematical constant that is approximately equal to 3.14159. It is the same value for all circles, regardless of their size.

5. Can the area of a circle be negative or zero?

Ans. No, the area of a circle cannot be negative or zero. The area represents the amount of space enclosed by the circle, so it is always a positive value. If the radius or diameter is zero, the circle does not exist, and therefore, it has no area.
