Area of Circle
What is the Area of Circle?
The region bounded by the circle is called as the area of the circle.
How is the area of a circle different from its circumference?
The area of a circle represents the total space enclosed by its circumference, while the circumference is the distance around the outer edge of the circle.
Can the area of a circle be negative?
No, the area of a circle cannot be negative. It is always a positive value or zero.
How does changing the radius of a circle affect its area?
Increasing the radius of a circle increases its area proportionally, following the formula A = πr². Conversely, decreasing the radius reduces the area accordingly.
What are some practical applications of knowing the area of a circle in real-life scenarios?
Real-life applications include calculating areas of fields, ponds, or circular plots of land, determining the amount of material needed for circular constructions like roads or pipes, and designing circular objects such as wheels or discs.
