In this tutorial will get circle radius from user and calculate area and prints it using following formulaArea = PI X r X r
import java.util.Scanner;
public class MathGeometry8 {
public static void main(String[] args) {
double circleRadius;
Scanner in = new Scanner(System.in);
System.out.println("Please enter the radius of circle:");
circleRadius = in.nextDouble();
double areaOfCircle = Math.PI * (circleRadius * circleRadius);
System.out.println("Area of circle is: " + areaOfCircle);
}
}
Output:
Please enter the radius of circle:
3.2
Area of circle is: 32.169908772759484
