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.
