URI-1011 Solve

Sphere

Adapted by Neilor Tonin, URI  Brazil

Timelimit: 1

Make a program that calculates and shows the volume of a sphere being provided the value of its radius (R) . The formula to calculate the volume is: (4/3) * pi * R3. Consider (assign) for pi the value 3.14159.

Tip: Use (4/3.0) or (4.0/3) in your formula, because some languages (including C++) assume that the division's result between two integers is another integer. :)

Input

The input contains a value of floating point (double precision).

Output

The output must be a message "VOLUME" like the following example with a space before and after the equal signal. The value must be presented with 3 digits after the decimal point.

Input Samples	Output Samples
3	VOLUME = 113.097

15	VOLUME = 14137.155

1523	VOLUME = 14797486501.627

Solution:

• [tab]
• C

• #include <stdio.h>
  #include <math.h>
  #define pi 3.14159
  int main ()
  {
      float r;
      while (scanf("%f",&r) != EOF)
      {
          printf("VOLUME = %.3f\n",(4/3.0)*pi*(r*r*r));
   
      }
      return 0;
   
  }

• C++

• #include <cstdio>
  #include <cmath>
  
  int main()
  {
   int a;
  
   scanf("%i", &a);
   printf("VOLUME = %.3lf\n", (4 * 3.14159 * pow(a, 3)) / 3);
  
   return 0;
  }
