Sphere

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

Answer

#include<stdio.h>
int main()
{
    double sum,R,pi=3.14159;
    scanf("%lf",&R);
    R=R*R*R;
    sum=(4.0/3)*pi*R;
    printf("VOLUME = %.3lf\n",sum);
    return 0;
}
