Write a C$++$ program that takes the radius of a sphere $($a double or floating$-$point number$)$ as input and then outputs the sphere's:

$1.$ Diameter $=(2$ x radius$)[$diameter $=2*$radius$]$

$2.$ Circumference $=($diameter x pi$)[$circumference $=$ diameter $*$ math.pi$]$

$3.$ Surface area $=(4$ x pi x radius$^2)[$surface area $=4*$math$.$pi$*$radius$*$radius$]$

$4.$ Volume $=(4/3$ x pi x radius$^3)[$volume $=4/3*$math$.$pi$*$radius$*$radius$*$radius$]$

Below is an example of the program input and output:

display$/$introduce $($a message of$)$ what the program will accomplish

radius $=5$

diameter : $10\mathrm{.}0$

circumference : $31\mathrm{.}4159265389793$

surface area : $314\mathrm{.}159265389793$

volume : $523\mathrm{.}5987755982989$
