Java program to input the radius and height of a cylinder and find its volume and total surface area

Write a program to input the radius and height of a cylinder and find its volume and total surface area.

Note: Total Surface Area=22 + 2h

Volume=2h

import java.util.*;
class AreaCylinder 
{
	public static void main(String arr[])
	{
		Scanner sc=new Scanner(System.in);
		float r,h,v,a,pi=3.142f;
		System.out.println( “Enter the radius:”);
		r=sc.nextFloat();
		System.out.println( “Enter the height:”);
		h=sc.nextFloat();
		v=pi*r*r*h;
		a=2*pi*r*r+2*pi*r*h;
		System.out.println( “ Volume=”+v);
		System.out.println( “Area=”+a);
	}
}
