Objectives: To use library functions to evaluate equations. To understand nested loop structures,

both $$for$$ and $$while$.$

Problem$1$:

$1.$ Add a line that prompts the user to enter the diameter of a sphere.

$2.$ Read in and store the number into a variable called diameter $($you will need to declare any

variables that you use$).$

$3.$ The diameter is twice as long as the radius, so calculate and store the radius in an appropriately

named variable.

$4.$ The formula for the volume of a sphere is: V $=4/3*3$

Convert the formula to C$++$ code and add a line which calculates and stores the value of volume in an

appropriately named variable. Use pow$($x$,$y$)$ to cube the radius.

$5.$ Print your results to the screen with an appropriate message.
