The area of a circle is the total amount of space that is enclosed within the boundaries of a circle. In other words, the total number of square units in a circle is the area of a circle. A circle is a two-dimensional shape. Hence, it has only circumference/perimeter and area. It does not have volume. The mathematical formula for the area of a circle is πr.r where r is the radius of the circle.

Radius: The distance from the center of the circle to any given point. It is represented by ‘r’.
Diameter: A line that passes through the center of the circle to its endpoints. It is represented by ‘d’.
Here is an example to solve a question on an area of a circle. Let’s look at the given example mentioned below to understand more about the area of the circle.
Area of Circle = πr.r
where r is the radius of the circle.
Q. Calculate the area of a circle if the radius of the circle is 5 cm ?
ATQ,
Radius of the circle = 5 cm
Use the area of circle formula = ㅠr.r
3.14 * 5 * 5 = 3.14 * 25
3.14 * 25 = 78.5 cm square units.
Answer: 78.5 cm square units.
