Question

Write a menu driven program to find area of a circle volume of a sphere total surface area of cuboid

Answer 1

import java . util.*;

class calculation

{

//space//Scanner sc=newScanner(System.in);

void main()

{

double//space//v=0.0,area=0?0,sa=0.0,r,pie=3.147;

int//space//l,b,h,ch;

System.out.println("1.area");

System.out.println("2.volume");

System.out.println("3.surface area");

System.out.println("enter your choice");

ch=sc.nextInt();

System.out.println("enter radius");

r=sc.nextDouble();

switch(ch);

{

//space//case 1:

//space//area=pie*r*r*r;

//space//System.put.println("area="+area);

break;

//space//case 2:

//space//v=4/3*pie*r*r*r;

//space//System.out.pri tln("volume="+v);

break;

//space//case 3:

//space//System.out .println("enter length,breath,height of a cuboid");

//space//l=sc.nextInt();

//space//b=sc.nextInt();

//space//h=sc.nextInt();

//space//sa=2(lh+bh+lb);

//space//System.out.println("surface area="+sa);

break;

//space//default:

//space//System.out.println("invalid choice");

}

}
