LabTask wk01. Write a program to calculate the volume of spheres, cylinders and boxes. Your program should contain three functions, each called calcVolume and returning a double. The volumes should be calculated according to the following formulas: -- The volume of a box is its width multiplied by its height multiplied by its length. an The volume of a sphere is -43 rr3 wherer is the radius of the sphere. -- The volume of a cylinder is rur2h, wherer is the radius of the cylinder and his the height of the cylinder. Define a global constant PI and set its value to 3.14. Your program should ask the user which shape's volume they want to calculate, and get the required information. It should then call the correct calcVolume function and output the volume to the screen. Lab02-01. What does Listing 1-1 do?
