How to Calculate Area of Circle in Java?
Because the area of a circle is the product of its radius squared and the value of PI, the area of a rectangle is calculated in the same way.
1. Calculate the circle’s radius.
2. Determine the radius’s square.
3. Determine the product of the value of PI and the value of the radius squared.
4. The output should be printed.
Importance of area of a circle java program?
According to Study.com, area is a mathematical term defined as the two-dimensional space occupied by an object.
The use of area has many practical applications in building, farming, architecture, science, and even how much carpet you’ll need to cover the rooms in your house.
Example Code:
//Program to find the area of circle in java: Example Code
int radius;
double area;
Scanner sc = new Scanner(System.in);
System.out.println("Enter the radius of the circle ::");
radius = sc.nextInt();
area = (radius * radius) * Math.PI;
System.out.println("Area of the circle is ::" + area);
