Answer to Question #244000 in C for theblacksun

Question

Given the values for radius and height of a Cylinder, code a C program to calculate the Surface Area of the Cylinder. Function CalculateArea must accept height and radius as parameters. 

$$A = 2\pi rh + 2\pi r^2$$

r = radius

h = height

Answer 1

#include <stdio.h>
#include <math.h>

float CalculateArea(float r, float h) {
  return 2.f * M_PI * r * h + 2.f * M_PI * r * r;
}

int main()
{
  float r, h;
  printf("Radius: ");
  scanf("%f", &r);
  printf("Height: ");
  scanf("%f", &h);
  printf("Cylinder's Area: %0.4f\n", CalculateArea(r, h));

  return 0;
}
