计算圆柱体的体积

编写程序，读入圆柱体的半径，高，并使用公式计算圆柱的面积，体积

public class ricals {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
Scanner input =new Scanner(System.in);
final double PI=3.14159;

System.out.println("Enter the radious  of a cylinder:");
int radious =input.nextInt();

System.out.println("Enter the length  of a cylinder:");
int length=input.nextInt();

double area=radious * radious*PI;
double volume =area*length;

System.out.println("the area is "+area);
System.out.println("the volume is "+volume);

	}

}

输出：
