It is represented by the letter 'r' or 'R'. Radius: The distance from the center to a point on the boundary is called the radius of a circle. The measure of the space or region enclosed inside the circle is known as the area of the circle. We see circles in everyday life such as a wheel, pizzas, a circular ground, etc.

A circle is a collection of points that are at a fixed distance from the center of the circle. Let us recall the circle and its parts before learning about area of circle in detail. 1.ĭifferences Between Area and Circumference of a Circle Let us learn in detail about the area of a circle, surface area, and its circumference with examples. A circle only has an area and perimeter/circumference. A circle is a two-dimensional shape, it does not have volume. Does a circle have volume? No, a circle doesn't have a volume. Suppose, if you have a circular table, then the area formula will help us to know how much cloth is needed to cover it completely. The area of a circle formula is useful for measuring the region occupied by a circular field or a plot. The unit of area is the square unit, for example, m 2, cm 2, in 2, etc. The formula for the area of a circle is A = πr 2, where r is the radius of the circle. Alternatively, the space occupied within the boundary/circumference of a circle is called the area of the circle.

The area of a circle is the space occupied by the circle in a two-dimensional plane.
