Given sphere$\_$radius and pi$,$ compute the volume of a sphere and assign to sphere$\_$volume. Volume of sphere $=(4\mathrm{.}0/3\mathrm{.}0)$ r$3$

Sample output with input: $1\mathrm{.}0$

Sphere volume: $4\mathrm{.}19$

$0\mathrm{.}714285714286$

Complete the program as follows:

Write a line of code that reads an integer value from input into user$\_$num$3.$

Write a print$()$ statement that outputs the product of user$\_$num$1,$ user$\_$num$2,$ user$\_$num$3.$

Note:

The product is user$\_$num$1*$ user$\_$num$2*$ user$\_$num$3.$

Our autograder automatically runs your program several times, testing different input values each time to ensure your program works for any values.
