Write a C program to enter radius of a circle and find its diameter, circumference and area. /* diameter = 2 r circumference = 2 pi r Area = pi r * r */ Static #include<stdio.h> #include<conio.h> void main() {     clrscr();     float pi = 3.14,dia,cir,area;     int r = 10;     dia = 2 * r;     cir = 2 * pi * r;     area = pi * r * r;     printf("\nThe area of circle :- %f",area);     printf("\nThe diameter of a circle :- %f",dia);     printf("\nThe circumference of a circle :- %f",cir); getch(); }    Output :-  Dynamic   #include<stdio.h> #include<conio.h> void main() {     clrscr();     float pi = 3.14,dia,cir,area;     int r;      printf("Enter the radius :- ");     scanf("%d",&r);     dia = 2 * r;     cir = 2 * pi * r;     area = pi * r * r;     printf("\nThe area of circle :- %f",area);     printf("\nThe diameter of a circle :- %f",dia);     printf("\nThe circumference of a circl
