How to express the volume of a ball in C language

In C language, the volume expression formula of the ball is volume = (4/3) PI radius^3, where radius is the radius of the ball and PI is the pi constant (approximately 3.14159265).

The volume of the ball in C language is expressed

In C language, the volume of the ball can be expressed by the following formula ：

<code class="c">volume = (4/3) * PI * radius^3</code>

Where:

• volume：The volume of the ball
• radius：The radius of the ball
• PI: Pi is a constant about 3.14159265, which can be defined by #define PI 3.14159265

Example:

Suppose there is a sphere with a radius of 5, its volume can be calculated as follows:

<code class="c">#include <stdio.h>

#define PI 3.14159265

int main() {
    float radius = 5;
    float volume = (4/3) * PI * radius * radius * radius;

    printf("球的体积为：%.2f\n", volume);

    return 0;
}</code>

Run this program, the following output will be printed:

<code>球的体积为：523.60</code>
