Area Of A Circle

Introduction

Calculating the area of a circle is a fundamental mathematical operation. In this article, we will discuss an iterative approach to finding the area of a circle. We will cover the understanding of the circle's properties, the approach to finding the area, and provide a step-by-step solution with sample code.



 Understanding the Circle

A circle is a geometric shape consisting of all points in a plane that are equidistant from a fixed center point. The distance from the center point to any point on the circle is called the radius (r), and the ratio of the circumference of the circle to its diameter is represented by the mathematical constant pi (π).



 Approach

To find the area of a circle, we can use the formula A = π * r^2, where A represents the area and r is the radius of the circle. By squaring the radius and multiplying it by the value of π, we can calculate the area of the circle iteratively.
