Area=(pi*r*l) + (pi*r*r)
Enter the radius and height of cone as input. Now we calculate the surface area and volume by using formula and get the desired output.
Here is the source code of the Java Program to Find the Surface Area and Volume of a Cone. The Java program is successfully compiled and run on a Windows system. The program output is also shown below.
public class SurfaceArea_Volume
public static void main(String args)
int r, h;
double l, area, volume, pi = 3.14;
Scanner s = new Scanner(System.in);
System.out.print("Enter the height of cone:");
h = s.nextInt();
System.out.print("Enter the radius of cone:");
r = s.nextInt();
l = Math.sqrt((r * r) + (h * h));
area = (pi * r * l) + (pi * r * r);
System.out.println("Surface Area of cone:"+area);
volume = 0.333 * pi * r * r * h;
System.out.println("Volume of cone:"+volume);
