Volume and Surface Area of Sphere 4 V = πr³ 3 A = 4πr² Program Project 4.3. Write a class called sphere that contains an instance variable that represents the sphere's radius. Make this a double. Define a Sphere constructor that initializes the sphere's radius. public Sphere (double r Include setter and getter methods that set and get the radius. public double getRadius(); public void setRadius (double radius) Include a method that returns the sphere's volume and a method that returns the sphere's area. Include a tostring(y method that returns a brief string that shows the radius, area, and volume. public double azea(); public double volume(); public String tostring(0) Just write the class definition for sphere. There will be no main method for this class. Use the BlueJ interface to create sphe-objects and test the methods.
