I want you to write a short program that asks the user for a number that is the radius of a circle and stores that value in a variable of type double called radius. Then display on the screen the perimeter of a circle with that radius. In case you forgot the formula to calculate perimeter is $2*$ radius $*3\mathrm{.}14$ or whatever approximation of Pl you want to use.Sample OutputEnter radius:$4\mathrm{.}5$Perimeter: $28\mathrm{.}26$
