Homework  

Create a program that calculates the areas and volumes of
various 3D geometric objects: cylinders, cones, cubes and spheres.

These following formulas are written in "English math" because this is a text file.

The formula for the area of a cylinder is:
(two times pi times radius times height) 
 plus 
(two times pi times (radius squared))


the formula for the area of a sphere is:
four times pi times (radius squared)


formula for area of a cone:
(pi times radius times (square root of (radius squared) plus (height squared)))
 plus 
(pi times (radius squared))


formula for area of a cube:
six times (side length squared)  Let the side length be "height"


Volume of sphere:
four-thirds times pi times (radius cubed)


Volume of cylinder:
pi times (radius squared) times height


Volume of cone:
one-third times pi times (radius squared) times height


Volume of a cube:
height cubed


Input from the user the radius and height of the solids. 
Use the same values for all the solids (i.e. input them only once).
You are writing one program that does all 8 calculations.

Have a variable for each of the 8 areas and volumes (i.e. 8 variables, well-named).

Display the results tabularly like the following:
------------------------------------------------
radius  xx
height  xx

Solid       Area             Volume
-----       -----            ------
cone        xx.xx            xx.xx
sphere       x.xx             x.xx
cylinder    xx.xx             x.xx
cube         x.xx             x.xx

where the x's are the actual values.  Don't worry about aligning the
columns perfectly.

Hint: don't write all this at once; build it up piece by piece.
Create the basic input and one output first, then when
that works add some of the other geometric objects.

Print the source code file and turn in.
Upload the source code in LEO Assignment.

Here's an example to check your work by:
 height 1 and radius 1 

 cone surface area is 7.584
 sphere surface area is 12.566
 cylinder surface area is 12.566
 cube surface area is 6

 cone  Volume is 1.047
 sphere  Volume is 4.189 
 cylinder  Volume is 3.142
 cube Volume is 1
