Area and Perimeter of circle

Explanation

Area of circle

You are already quite familiar with the concept of the circle. Here, in this lesson, we will study the area of the circle. In the course of learning the concept of the area of the circle, we will come across the area of circle formula, and the perimeter of circle formula. You would also be able to work on the examples where you can practice at the end of this chapter.

What is area of circle?

The region which is occupied by the circle in a 2-dimensional plane is known as the area of a circle. One can determine the area of a circle by using the formula A =2 πr² Here, ‘r’ denotes the radius of the circle.  Measuring the space which is occupied by a circular field or a plot becomes easier by making use of the area formula. It is also possible to calculate the perimeter as well as the area of the circle with the use of different formulas. It is also important to understand that a circle does not have a volume that creates confusion in the minds of the students. It is because the volume is not present in a circle, since circle is a 2-D shape and not a 3-D solid figure.
