#include
int main()
{
const double pi = acos(-1.0);
double r, h, s1, s2, s;
scanf("%1f%1f", &r, &h);
s1 = pi*r*r;
s2 = 2*pi*r*h;
s = s1*2.0 + s2;
printf("Area = %.3f\n", s);
return 0;
}

Answer 1

const double pi = acos(-1.0);

float r, h, s1, s2, s;
scanf("%f %f", &r, &h);
s1 = pi*r*r;
s2 = 2*pi*r*h;
s = s1*2.0 + s2;
printf("Area = %f\n", s);
return 0;
