使用c语言，计算圆柱体的表面积

#include <stdio.h>

int main() {
float radius, height, surface_area;

printf("Enter radius of cylinder: ");
scanf("%f", &radius);

printf("Enter height of cylinder: ");
scanf("%f", &height);

surface_area = 2 * 3.14 * radius * height + 2 * 3.14 * radius * radius;

printf("Surface area of cylinder is: %f", surface_area);

return 0;
}
