Write static methods: public static double sphereVolume(double r) :Tr3 public static double sphereSurface(double r) : 47tr2 public static double coneVolume(double r, double h): – thr2 public static double coneSurface(double r, double h) :ar(h +r) that compute the volume and surface area of a sphere with radius r, and a cone with circular base with radius r and height h. Place them into a class "Geometry2.java". Then write a program with main class called “Lab7_yourID.java" that prompts the user for the values of r and h, calls the four methods, and prints the results.

Exercise 3: A. Write static methods: public static double sphereVolume(double r) :Tr3 public static double sphereSurface(double r) : 4ar2 public static double coneVolume(double r, double h): – thr² public static double coneSurface(double r, double h) :7r(h+r) 1 3 that compute the volume and surface area of a sphere with radius r, and a cone with circular base with radius r and height h. Place them into a class "Geometry2.java". Then write a program with main class called "Lab7_yourID.java" that prompts the user for the values of r and h, calls the four methods, and prints the results. B. (Optional) Reconsider your previous solution by implementing classes Sphere, and Cone separately instead of a single class "Geometry2" (part A). Which approach is more object-oriented? Extra Geometry to try: Area of Plane Shapes Area is the size of a surface! Learn more about Area, or try the Area Calculator.
