An area is a region bounded by a shape. In mathematics, it is used to measure the amount of space inside a shape. To determine the area of a circle, we need to understand the concept of circumference, which is the length of the border of the circle.
A circle is a plane figure with no corners or edges. It is defined by the distance from the center to any point on the circle. The radius is the distance from the center to the outside edge of the circle. The diameter is the length of the line connecting the two ends of the radius.
The area of a circle is calculated by multiplying the radius squared by π. The formula is:
A = πr²
where:
A is the area of the circle in square units
π is a mathematical constant approximately equal to 3.14
r is the radius of the circle in units
