Exercise 3: A Write static methods: public static double sphereVolume(double r):r³ public static double sphereSurface(double r) 4r public static double coneVolume(double r, double h) hr public static double coneSurface(double r, double h) :r(h+r) 3. that compute the volume and surface area of a sphere with radiusr, 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 Cube, and Cylinder separately instead of a single class "Geometry2" (part A). Which approach is more object-oriented?
