Solve Exercise E8.11 by implementing classes Sphere, Cylinder, and Cone. Which approach is more object-oriented?

Data from Exercise E8.11

Write static methods

• public static double sphereVolume(double r)
• public static double sphereSurface(double r)
• public static double cylinderVolume(double r, double h)
• public static double cylinderSurface(double r, double h)
• public static double coneVolume(double r, double h)
• public static double coneSurface(double r, double h)

that compute the volume and surface area of a sphere with a radius r, a cylinder with a circular base with radius r and height h, and a cone with a circular base with radius r and height h. Place them into a class Geometry. Then write a program that prompts the user for the values of r and h, calls the six methods, and prints the results.
