For your homework, write a program that computes the surface area of a cylinder. Your program should read in the height of the cylinder and radius of the base, and it should both compute and output the surface area of the cylinder (being as exact as possible). Comment your solution here.
class Main { public static void main(String[] args) { double h = 3.5; double r = 4.0; double s = 2 * r * r * Math.PI + 2 * Math.PI * r * h; System.out.println(s); } }
import java.util.Scanner; class Main { public static void main(String[] args) { System.out.println(" Please enter the radius of the cylinder. " ); Scanner sc = new Scanner(System.in); float radius = sc.nextFloat(); System.out.println(" Please enter the height of the cylinder. " ); float height = sc.nextFloat(); double area = 2 * radius * radius *Math.PI + 2 * radius *Math.PI * height; System.out.println(" The Surface Area is ..." ); System.out.println(area); } }
import java.util.Scanner; class Main { public static void main(String[] args) { System.out.println("enter the radius" ); Scanner sc = new Scanner(System.in); float r = sc.nextFloat(); System.out.println("enter the height" ); float h = sc.nextFloat(); double sa = 2 * r * r *Math.PI + 2 * r *Math.PI * h; System.out.println(" The Surface Area is " + sa ); } }
