Program Plan Intro

Calculate the area and volume of sphere

Program plan:

• Import the required packages
• The function named “sphereArea()” is defined and inside the “sphereArea()”,
  • Declare the variable named “area” and store the calculated area value in it.
  • Return the value stored in the “area” variable.
• The function named “sphereVolume()” is defined and inside the “sphereVolume()”,
  • Declare the variable named “volume” and store the calculated volume value in it.
  • Return the value stored in the “volume” variable.
• In the “main()” function,
  • Generate a prompt to take the user input.
  • Call the method named “sphereArea()” with user input as the argument.
  • Call the method named “sphereVolume()” with user input as the argument.
• Print the output statement and output value.
• Call the function “main()”.
