Write a program that prompts the user for a radius and then prints
• The area and circumference of a circle with that radius
• The volume and surface area of a sphere with that radius

Example:

Please enter Radius: 25
Area of circle: 1963.4954084936207
Circumference of circle: 157.07963267948966
Volume of sphere: 65449.84694978735
Surface area of sphere: 7853.981633974483

Code:

```import java.util.Scanner;

public class Main
{
public static void main(String[] args) {

Scanner input = new Scanner(System.in);
double radius;
System.out.print("Please enter Radius: ");

radius = input.nextDouble();
input.close();

System.out.println("Area of circle: " + (Math.PI * Math.pow(radius, 2)));
System.out.println("Circumference of circle: " + (2 * Math.PI * radius));
System.out.println("Volume of sphere: " + (4.0 / 3.0 * Math.PI * Math.pow(radius, 3)));
System.out.println("Surface area of sphere: "+ (4.0 * Math.PI * Math.pow(radius, 2)));

}
}
```
