Calculating the Volume of a Sphere in Go

To calculate the volume of a sphere in Go, you can use the following formula:

V = (4/3) π r^3

Where: - V is the volume of the sphere - π (pi) is a mathematical constant approximately equal to 3.14159 - r is the radius of the sphere

Here's an example code snippet that calculates the volume of a sphere in Go:

package main

import (
    "fmt"
    "math"
)

func main() {
    radius := 5.0
    volume := (4.0 / 3.0)  math.Pi  math.Pow(radius, 3)
    fmt.Printf("The volume of the sphere with radius %.2f is %.2f\n", radius, volume)
}

In this code, we import the fmt package for printing the result and the math package for accessing the mathematical constant Pi and the Pow function for exponentiation. We then define the radius of the sphere as 5.0 and calculate the volume using the formula. Finally, we use fmt.Printf to print the result.

When you run this code, it will output:

The volume of the sphere with radius 5.00 is 523.60

This means that a sphere with a radius of 5 units has a volume of 523.60 cubic units.
