Part III: Picking up the pieces (25 points) Write a function capsule volume () that computes the volume of material required to create a rounded, cylin- drical metal capsule with walls of a provided thickness. The function takes three arguments that provide the dimensions of the capsule: . | 3 th thickness Note that each end of the capsule is hemispherical. The radius of each hemisphere is the same as the radius of the cylindrical part of the capsule. As shown in the figure above, the cavity inside the capsule is also cylindrical with hemispherical ends. The thickness of the wall determines the radius of the cavity (Hint can you derive a formula to get the radius of the cavity?) or You will find the following formulas helpful: to your code Volume of a sphere of radius r: fer Volume of a cylinder of radius r and height: ar In your code, you must use math.pl to perform the computations, or else it is likely your code incorrect results Your code must also do some basic error checking Specifically, if the length of the capsule is less than or equal to two times the radius, return the floating point value-1.0 to indicate invalid parameters. Or, if any of the three arguments is or negative, return -1.0.
